Given a string, an integer position, and a character, all on separate lines, find the character of the string in that position and replace it with the character read. Then, output the result.
Ex: If the input is:
warn
0
e
the output is:
earn
Note: Using a pre-defined string function, the solution can be just one line of code.
Answer:
The program in Python is as follows:
myStr = input()
pos = int(input())
chrr = input()
myList=[]
myList[:0]=myStr
myList[pos] = chrr
myStr =""
for i in myList:
myStr+=i
print(myStr)
Explanation:
This gets input for the string
myStr = input()
This gets input for the character position
pos = int(input())
This gets input for the incoming character
chrr = input()
Create an empty list
myList=[]
Convert the string to a list
myList[:0]=myStr
Replace the character
myList[pos] = chrr
Empty the string
myStr =""
Get the new string
for i in myList:
myStr+=i
Print the new string
print(myStr)
Following are the C++ program to replace the first index value of the string.
Program Explanation:
Defining header file.Defining the main method.Inside the main method three variable "Sval, Spos, Subchar" is declared in which "string, int, and char".After input variable value a string variable is declared with the at (method), which replaces the first index value with the character value.After replacing the first index value that is "0" use the prints method that prints its value.Program:
#include <iostream>//header file
#include <string>//header file
using namespace std;
int main() //main method
{
string Sval;//defining string variable
int Spos;//defining integer variable
char Subchar;//defining char variable
cin>>Sval>>Spos>> Schar;//input value
Sval.at(Spos) = Subchar; //using string variable that replaces the first index value with the character value
cout << Sval << endl;//printing the replaced value
return 0;
}

A Human representatives will not be needed to respond to some inquiries.
B
The company will be able to provide a human representative for any incoming call.
с
Customers are likely to spend less time listening to information not relevant to their issue.
D
Customers will be unable to mistakenly select the incorrect department for their particular issue.
Answer:
The company will be able to provide human representative for any incoming call
Explanation:
The upgrade of a system is meant to resolve identified issues in an initial system and given that the available human representative is usually less than the number of incoming call at a given time, due to a constant drive for a larger customer base, we have;
The upgraded system will provide technologies such that human representative will not be required for some inquiries, customers will listen to mainly relevant information with regards to their issues and customers will be properly directed to the correct department that are concerned with their current issue
Therefore, the LEAST likely goal of the upgraded system from among the options and therefore the least likely to be provided by the upgrade is the company will be able to provide human representative for any incoming call

an_is a sepuence of precise instructions which result in a solution
Answer:
algorithm.
Explanation:
An algorithm can be defined as a standard formula or procedures which comprises of set of finite steps or instructions for solving a problem on a computer. The time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the input.
Furthermore, the processing symbols and their functions used in developing an algorithm are oval (start or stop), diamond (decision-making), circle (on-page connector), parallelogram (input and output), rectangle (calculation), arrow (flow or direction) and pentagon (off-page connector).
Some of the characteristics of an algorithm include the following;
I. An algorithm can be written using pseudocode. A pseudocode refers to the description of the steps contained in an algorithm using a plain or natural language.
II. An algorithm can be visualized using flowcharts. A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.
In conclusion, an algorithm is a sequence of precise instructions which result in a solution for solving problems using a computer system.
Q.No.2. A study of the effect of smoking on sleep patterns is conducted. The measure observed is the time, in minutes, that it takes to fall asleep. These data are obtained: [3] Smokers:69.3 56.0 22.1 47.6 53.2 48.1 52.7 34.4 60.2 43.8 23.2 13.8 Non Smokers: 28.6 25.1 26.4 34.9 28.8 28.4 38.5 30.2 30.6 31.8 41.6 21.1 36.0 37.9 13.9
Answer:
(a) [tex]\bar x_1 = 43.7[/tex] [tex]\bar x_2 = 30.25[/tex]
(b) [tex]\sigma_1 = 16.93[/tex] [tex]\sigma_2 = 7.14[/tex]
(c) Smoking increases the time to fall asleep
Explanation:
Solving (a): The sample mean of each group
Mean is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
So, we have:
Smokers
[tex]n_1= 12[/tex] and
[tex]\bar x_1 = \frac{69.3 +56.0+ 22.1 +47.6+ 53.2+ 48.1+ 52.7 +34.4+ 60.2 +43.8 +23.2 +13.8}{12}[/tex]
[tex]\bar x_1 = \frac{524.4}{12}[/tex]
[tex]\bar x_1 = 43.7[/tex]
Non Smokers
[tex]n_2 = 15[/tex] and
[tex]\bar x = \frac{28.6 +25.1 +26.4 +34.9 +28.8 +28.4 +38.5 +30.2 +30.6 +31.8 +41.6 +21.1 +36.0 +37.9 +13.9}{15}[/tex]
[tex]\bar x_2 = \frac{453.8}{15}[/tex]
[tex]\bar x_2 = 30.25[/tex]
Solving (b): The standard deviation of each group
This is calculated as:
[tex]\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
For smokers
[tex]n_1= 12[/tex]
So:
[tex]\sigma_1 = \sqrt{\frac{(69.3 -43.7)^2+(56.0-43.7)^2+..........+(13.8-43.7)^2}{12-1}}[/tex]
[tex]\sigma_1 = \sqrt{\frac{3152.04}{11}}[/tex]
[tex]\sigma_1 = \sqrt{286.5491}[/tex]
[tex]\sigma_1 = 16.93[/tex]
For non-smokers
[tex]n_2 = 15[/tex]
So:
[tex]\sigma_2 = \sqrt{\frac{(28.6 -30.25)^2+(25.1 -30.25)^2+..........+(13.9 -30.25)^2}{15-1}}[/tex]
[tex]\sigma_2 = \sqrt{\frac{713.2575}{14}}[/tex]
[tex]\sigma_2 = \sqrt{50.9469}[/tex]
[tex]\sigma_2 = 7.14[/tex]
Solving (c): Impact of smoking on time to sleep
In (b), we have:
[tex]\sigma_1 = 16.93[/tex] --- smokers
[tex]\sigma_2 = 7.14[/tex] --- non-smokers
Smokers have larger standard deviation (i.e. large variability) than non-smokers. This means that smokers require more time to fall asleep.

Define the followimg terms as it relates to coding.
Expression
Variable
Assignment operator
Answer and Explanation:
In coding, an expression is used to represent values. It may contain variables and/or constant.
Examples of expressions are:
[tex]a - b[/tex] [tex]a * 2[/tex] [tex]4 - 3[/tex]
Variables are literally memory locations. They are used to storing values, and they assume the values they store during program execution.
At any point in the program, the value of the variable can be changed.
Lastly, there are guidelines that follow naming variables (depending on the programming language).
Examples of accepted variable names (in C++) are:
num, num_1, num1
Assignment operator
This is the = sign. It is used for assigning values to variables.
Examples of how it is used are:
[tex]num1 = a - b[/tex]
[tex]num\_1 = a*2[/tex]
[tex]num = 4 - 3[/tex]
The following is a wrong usage of the operator
[tex]4 - 3 = num[/tex]

The lesson discusses ten "best practices" for digital recordings. Identify three of them and explain why they are important for ensuring a quality product.
(For a Digital Media Course)
Solution :
Digital recording may be defined as the preservation of an audio or some visual signals like the series of a binary numbers which can be stored on a magnetic tape or on an optical disc or some other digital storage media.
Some of the best practices for doing digital recording are :
1. We should always take permission from those who are being recorded. It is not right to shoot others without their permission. It is against the right to privacy.
2. We should record audio at about 44.1 kHz/16 bit in an uncompressed wave format.
3. A High quality MP3 (192 kbps or higher) is often accepted due to the limitations of a recorder or for a storage space.
The MP3 recordings are considered as the best option for certain recorders and when the storage space is severely limited. It produces a good quality recording.
