Answer:
Following are the method to the given question:
def copy(s, n):#defining a method copy that takes two parameters
if n <= 0:#definig if to compare n value is less than equal to 0
return ''#return space
else:#definig else block
return s + copy(s, n-1)#use recursive method that return value
print(copy("by",2))#calling method and print value
print(copy("ta",2))#calling method and print value
print(copy("good by ",2))#calling method and print value
Output:
byby
tata
good by good by
Explanation:
In this code, a method "copy" is declared that takes two parameters that are "s and n" inside the method a conditional statement is used which can be defined as follows.
In the if block is used "n" variable that checks n value which is less than equal to 0 if it is true it will return a space value.
In the else block it use the recursive method that returns a value which is a copy of s that is concatenated together.
During the data transmission there are chances that the data bits in the frame might get corrupted. This will require the sender to re-transmit the frame and hence it will increase the re-transmission overhead. By considering the scenarios given below, you have to choose whether the packets should be encapsulated in a single frame or multiple frames in order to minimize the re-transmission overhead.
Justify your answer with one valid reason for both the scenarios given below.
Scenario A: Suppose you are using a network which is very prone to errors.
Scenario B: Suppose you are using a network with high reliability and accuracy.
The packets would be encapsulated in single frame in scenario A. In scenario B, it should be in multi frames.
In scenario A, given that this network has been said to be prone to error, the packets should be encapsulated in single frames.
The reason for this is because, using a single frame helps to decrease error. We have been told already that it is prone to error. If you use the multi frame, there would be very high likelihood of errors occurring.
In scenario B, given that the network is accurate and very reliable, the best packet is the multi frame.
It would give a quicker transmission and the likelihood of errors occurring is also low.

cpp Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Ex: If the input is:
Answer:
#include <iostream>
int main() {
// The length of the list
int l;
// The array containing the numbers
int *list;
// Threshold, last value in array
int thresh;
// Read in first value and create an array with the size of that value
scanf("%d", &l);
list = (int*) malloc(l * sizeof(int));
for(int i = 0; i < l; i++) {
scanf("%d", &list[i]);
}
thresh = list[l - 1];
// Print the values
for(int i = 0; i < l - 1; i++) {
if (list[i] <= thresh) {
printf("%d ", list[i]);
}
}
printf("\n");
free(list);
}
Explanation:
The program assumes at least two values are provided. The length of the list and the threshold.
We first read in an integer, and find out how many more integers we need to read. We create an array with the appropriate size, and loop through to fill the array with values. We know the last value is the threshold, and so we do one more loop to compare the values in the array with the threshold.

Suppose we can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. We can redeem six coupons for one chocolate bar from the machine. This means that once you have started buying chocolate bars from the machine, you always have some coupons. We would like to know how many chocolate bars can be eaten if we start with N dollars and always redeem coupons if we have enough for an additional chocolate bar.For example, with 6 dollars we could consume 7 chocolate bars after purchasing 6 bars giving us 6 coupons and then redeeming the 6 coupons for one bar. This would leave us with one extra coupon. For 11 dollars, we could consume 13 chocolate bars and still have one coupon left. For 2 dollars, we could have consumed 14 chocolate bars and have two coupons left.Write a program that inputs a value for N and outputs how many chocolate bars we can eat and how many coupons we would have left over. Use a loop that continues to redeem coupons as long as there are enough to get at least one chocolate bar.
Answer and Explanation:
Using JavaScript:
/* program should take N input which represents the dollar amount and output how many chocolate bars and how many coupons we have*/
function chocolatebar(dollars){
var dollaramt= dollars;

A life insurance salesperson who takes advantage of the foot-in-the-door phenomenon would be most likely to:________
a. emphasize that his company is one of the largest in the insurance industry.
b. promise a free gift to those who agree to purchase an insurance policy.
c. address customers by their first names.
d. ask customers to respond to a brief survey of their attitudes regarding life insurance.
Answer:
d. ask customers to respond to a brief survey of their attitudes regarding life insurance.
Explanation:
A life insurance policy can be defined as a contract between a policyholder and an insurer, in which the insurer agrees to pay an amount of money to a specific beneficiary either upon the death of the insured person (decedent) or after a set period of time.
A salesperson (sales representative) refers to an individual or employee who is saddled with the responsibility of taking orders from customers, as well as selling finished goods and services to consumers or end users.
A foot-in-the-door phenomenon can be defined as a compliance (persuasive) technique or tactics that assumes a person agreeing to perform a small request increases the likelihood of he or she agreeing to a subsequent larger request. Thus, it posits that when a person agrees to a small, it makes it difficult for him or her to decline a second, larger (bigger) request.
In this context, a life insurance salesperson who takes advantage of the foot-in-the-door phenomenon would most likely ask his or her customers to respond to a brief survey of their attitudes regarding life insurance.

So we can maintain high quality designs at any graphic scale.
Explanation:
Unlike other graphic formats which simply define colors for fixed pixels, vector graphics define points and shapes (vectors) which are then used to draw the graphic at the desired and appropriate resolution.
Our graphic can look good at any resolution, no matter how large it gets. If we take a png or jpg file and make it extremely large, you'll notice the image begins to get blurry, because the pixels are being stretched and colors are being predicted or matched for the larger scale.

If Scheme were a pure functional language, could it include DISPLAY ? Why or why not?
Answer:
When Scheme is a pure functional language, it cannot include the function DISPLAY. Since the pure functional languages will return the same value whenever the same expression is evaluated, and the DISPLAY would be the output and thus it cannot be part of the purely functional language. Thus in the pure functional language we can evaluate the expressions with the same arguments and it returns the same value since there is no state to change.

WPA was created as a solution to the vulnerabilities in WEP/WEP2. Then, WPA was upgraded to WPA2.
WPA2 is the least vulnerable to hacks because for every user that is connected to the network through WPA2, a unique encryption is made available for such connection.
Hence, the most secure connection, of the 4 is WPA2.
c)what formula would be in the cell E2
Excel will generally be able to handle any properly-input mathematical formula, if valid operators are used. Commonly used operators include "+" (addition), "-" (subtraction), "*" (multiplication) and "/" (division). (Microsoft has a complete list of valid operators to be used in Excel formulas on the Office website). Here are some examples of formulas using common operators:
Formula Description
=C2-B2 Subtracts contents of B2 from contents of C2
=C2/B2 Divides contents of C2 by contents of B2
=(B2+C2+D2)/3 Adds contents of B2, C2, and D2 and divides result by 3
After hitting "Enter", the cell will display the calculated value, while the formula bar will still display the formula. (Note: Always hit “Enter” when finished entering a formula, manually. If you click off the cell, the cell you click to will be added to your formula.)Formulas
Formulas in Excel are basically mathematical expressions that use cell references (e.g., “A5”,” D17”) as arguments. For example, a formula that adds the contents of cell E5 and E6 could be written as follows:
= E5+E6
(Note: all formulas in Excel need to be preceded by an “=” sign.) If the values contained in E5 and E6 are 6 and 11, respectively, the formula will produce 17 as the value it displays. If you change E5 to 7, the result will automatically change to 18.
Example
Let's say you were putting together an office supply order, and you wanted to keep track of much you were spending. You could put together a spreadsheet like the one below, with the list of items to be purchased, their unit prices, the number of each item ordered, and the total spent for each. It would make sense to enter the things you know in advance (like the price of individual items and the number ordered), but you could let Excel calculate the totals for you. For the first item listed below (pencils), this could be done by making the value of the total price (cell D2), the value of the unit price (held in cell C2) multiplied by the number of items ordered (held in D2). This formula would be written "=B2*C2".
Once you click "OK", your completed formula will be input into the cell.
Copying and pasting formulas
Often, you will need Excel to do a series of similar computations, where the only things that will change are the cells used as arguments. For instance, in the example above, you would probably like Excel to calculate the Total Price for each item in the order. You could re-input the same formula used to get the total price for pencils in each cell in that row, just changing the cells referenced (i.e. "=PRODUCT(B3:C3)", "=PRODUCT(B4:C4)", etc.), but Excel has simpler method for this. If you have multiple cells in the same row or column that need to do the same computation, you can simply copy the value in the cell you entered a formula, and then paste it into the subsequent cells. Excel will then automatically adjust which cells are included in the formula, based upon which cell the formula was pasted to. So, if the original formula entered in D2 was "=PRODUCT(B2:C2)", the formula pasted into D4 would be "=PRODUCT(B4:C4)"
More simply, if you have a formula you want repeated in a number of directly adjoining cells, you can just click and drag the bottom right corner of the cell with the original formula (see image below) onto the cells you want the same formula entered, and Excel will automatically copy and paste the formula for you, with appropriate adjustments made to the cell numbers in the formula.
After selecting "PRODUCT" and clicking OK, you will get another dialog box, that allows you to select the cells to be multiplied. You can do this for individual cells, by selecting cells separately in the "Number1" and "Number2" boxes shown below, or by selecting an array of cells, by clicking and dragging on the range cells you want to use on the spreadsheet, itself. (Note: if you try to enter a formula in a cell using the Insert Formula button and there are adjacent cells with numbers, Excel will often select those cells automatically, so make sure the cells selected in the dialog box are the correct ones.) Excel also has built-in functions that can do a lot of useful calculations. These are most easily accessed by hitting the Insert Function button, which is represented by the “fx” symbol next to the formula bar. For example, instead of entering the formula shown above, the same result could have been achieved using the built-in "PRODUCT" function by clicking in cell D2 and hitting the Insert Formula button. This would give a dialog box like the one shown, below.
After choosing “PRODUCT” and pressing OK, a new dialogue box will appear where you may choose which cells should be multiplied. By selecting particular cells in the “Number1” and “Number2” boxes as shown below, you can do this for specific cells.
What is the formula would be in the cell E2Additionally, Excel contains many useful built-in functions that can perform calculations. The button shown by the “fx” sign next to the formula bar, “Insert Function,” can be used to access these the simplest way by clicking it.
Make sure the cells selected in the dialogue box are the proper ones because if you try to insert a formula in a cell using the Insert Formula button and there are adjacent cells containing numbers. Excel will frequently select those cells automatically.)
