In the following code segment, assume that the ArrayList numList has been properly declared and initialized to contain the Integer values [1, 2, 2, 3]. The code segment is intended to insert the Integer value val in numList so that numList will remain in ascending order. The code segment does not work as intended in all cases.
int index = 0;
while (val > numList.get(index))
{
index++;
}
numList.add(index, val);
For which of the following values of val will the code segment not work as intended?
a. 0
b. 1
c. 2
d. 3
e. 4
Answers
Answer:
e. 4
Explanation:
The code segment will not work as intended if the value of the variable val is 4. This is because the while loop is comparing the value of the variable val to the value of each element within the numList. Since there is no element that is bigger than or equal to the number 4, this means that if the variable val is given the value of 4 it will become an infinite loop. This would cause the program to crash and not work as intended.
The program illustrates the use of while loops.
The code segment will not work as intended when the value of val is 4
LoopsLoops are used to perform repeated operations
The programFrom the program, the while loop is repeated under the following condition:
val > numList.get(index)
This means that:
The loop is repeated as long as val has a value greater than the index of numList (i.e. 3)
From the list of options, 4 is greater than 3.
Hence, the code segment will not work as intended when the value of val is 4

A perpetual system of inventory can be defined as a method of financial accounting, which involves the updating informations about an inventory on a continuous basis (in real-time) as the sales or purchases are being made by the customers, through the use of enterprise management software applications and a digitized point-of-sale (POS) equipment.
Under a perpetual system of inventory, updates of the journal entry for cost of goods sold or received would include debiting accounts receivable and crediting sales immediately as it is being made or happening.
Hence, an advantage of the perpetual system of inventory over the periodic system of inventory is that, it ensures the inventory account balance is always accurate provided there are no spoilage, theft etc.
The following are the characteristic of a perpetual inventory system;
I. It is the most popular choice for modern business.
II. Inventory is updated in near real-time.
III. It provides up-to-date balance information and requires fewer physical counts.
Implement the method countInitial which accepts as parameters an ArrayList of Strings and a letter, stored in a String. (Precondition: the String letter has only one character. You do not need to check for this.) The method should return the number of Strings in the input ArrayList that start with the given letter. Your implementation should ignore the case of the Strings in the ArrayList. Hint - the algorithm to implement this method is just a modified version of the linear search algorithm. Use the runner class to test your method but do not add a main method to your U7_L4_Activity_One.java file or your code will not be scored correctly.

You've created a new programming language, and now you've decided to add hashmap support to it. Actually you are quite disappointed that in common programming languages it's impossible to add a number to all hashmap keys, or all its values. So you've decided to take matters into your own hands and implement your own hashmap in your new language that has the following operations:
insert x y - insert an object with key x and value y.
get x - return the value of an object with key x.
addToKey x - add x to all keys in map.
addToValue y - add y to all values in map.
To test out your new hashmap, you have a list of queries in the form of two arrays: queryTypes contains the names of the methods to be called (eg: insert, get, etc), and queries contains the arguments for those methods (the x and y values).
Your task is to implement this hashmap, apply the given queries, and to find the sum of all the results for get operations.
Example
For queryType = ["insert", "insert", "addToValue", "addToKey", "get"] and query = [[1, 2], [2, 3], [2], [1], [3]], the output should be hashMap(queryType, query) = 5.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 2, 2: 3}
3 query: {1: 4, 2: 5}
4 query: {2: 4, 3: 5}
5 query: answer is 5
The result of the last get query for 3 is 5 in the resulting hashmap.
For queryType = ["insert", "addToValue", "get", "insert", "addToKey", "addToValue", "get"] and query = [[1, 2], [2], [1], [2, 3], [1], [-1], [3]], the output should be hashMap(queryType, query) = 6.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 4}
3 query: answer is 4
4 query: {1: 4, 2: 3}
5 query: {2: 4, 3: 3}
6 query: {2: 3, 3: 2}
7 query: answer is 2
The sum of the results for all the get queries is equal to 4 + 2 = 6.

Consider the following code segment. int[][] arr = {{3, 2, 1}, {4, 3, 5}}; for (int row = 0; row < arr.length; row++) { for (int col = 0; col < arr[row].length; col++) { if (col > 0) { if (arr[row][col] >= arr[row][col - 1]) { System.out.println("Condition one"); } } if (arr[row][col] % 2 == 0) { System.out.println("Condition two"); } } } As a result of executing the code segment, how many times are "Condition one" and "Condition two" printed?
Answers
Answer:
Condition one - 1 time
Condition two - 2 times
Explanation:
Given
The above code segment
Required
Determine the number of times each print statement is executed
For condition one:
The if condition required to print the statement is: if (arr[row][col] >= arr[row][col - 1])
For the given data array, this condition is true only once, when
[tex]row = 1[/tex] and [tex]col = 2[/tex]
i.e.
if(arr[row][col] >= arr[row][col - 1])
=> arr[1][2] >= arr[1][2 - 1]
=> arr[1][2] >= arr[1][1]
=> 5 >= 3 ---- True
The statement is false for other elements of the array
Hence, Condition one is printed once
For condition two:
The if condition required to print the statement is: if (arr[row][col] % 2 == 0)
The condition checks if the array element is divisible by 2.
For the given data array, this condition is true only two times, when
[tex]row = 0[/tex] and [tex]col = 1[/tex]
[tex]row = 1[/tex] and [tex]col = 0[/tex]
i.e.
if (arr[row][col] % 2 == 0)
When [tex]row = 0[/tex] and [tex]col = 1[/tex]
=>arr[0][1] % 2 == 0
=>2 % 2 == 0 --- True
When [tex]row = 1[/tex] and [tex]col = 0[/tex]
=>arr[1][0] % 2 == 0
=> 4 % 2 == 0 --- True
The statement is false for other elements of the array
Hence, Condition two is printed twice

if service.lower() == "oil change":

elif service.lower() == "car wash":
print("Cost of car wash: $7")
elif service.lower() == "tire rotation":
print("Cost of tire rotation: $19")
else:
print("Invalid Service")
Explanation:
First, we prompt the user for the auto service
service = input("Enter desired auto service: ")
Next, we print the service entered
print("You entered: "+service)
Next, we check if the service entered is available (irrespective of the sentence case used for input). If yes, the cost of the service is printed.
This is achieved using the following if conditions
For Oil Change
if service.lower() == "oil change":
print("Cost of oil change: $35")
For Car wash
elif service.lower() == "car wash":
print("Cost of car wash: $7")
For Tire rotation
elif service.lower() == "tire rotation":
print("Cost of tire rotation: $19")
Any service different from the above three, is invalid
else:
print("Invalid Service")

Explanation:
The initialization that would allow the method to work as intended would be the following

This is because the method is looping through the array provided as an argument and comparing each word in the array with the word saved inside the variable called longest. The length of both are compared and if the word in the array is longer than the string saved in the variable longest then it is overwritten with the word in the array.
