You are given an array of integers. Your task is to create pairs of them, such that every created pair has the same sum. This sum is not specified, but the number of created pairs should be the maximum possible. Each array element may belong to one pair only.

Write a function

class Solution public int
solution (int[] A); }

that, given an array A consisting of N integers, returns the maximum possible number of pairs with the same sum.

Examples:
1. Given A = [1, 9, 8, 100, 2], the function should return 2. The pairs are (A[0]. A[1]) and (A[2], A[4]); the sum of each pair is 10.
2. Given A = [2, 2, 2, 3], the function should return 1. Although, for instance, A[0]+A[1] = A[0]+A[2], the pairs (A[0], A[1]) and (A[0], A[2]) cannot exist at the same time, because they both contain a common element, A[0].

Answer:

num1 = int(input("Enter value: "))

num2 = int(input("Enter value: "))

if num1 == num2:

   print("Equals.")

else:

   print("Unequal.")

Explanation:

The Boolean expression that tests if the value stored in the variable num1 is equal to the value stored in the variable num2 can be found in explanation.

A logical statement that could be either true or false is referred to as a Boolean expression.

As long as both parts of the expression have the same basic data type, Boolean expressions can compare data of any type. Data can be tested to see if it is the same as, greater than, or less than other data.

A Boolean expression is a type of expression used in programming languages that produces a Boolean value when evaluated. A Boolean value can only be true or false.

The boolean expression for the given scenario can be:

num1 = int(input("Enter value: "))

num2 = int(input("Enter value: "))

if num1 == num2:

  print("Equals.")

else:

  print("Unequal.")

Thus, above mentioned is the program for the given code.

What is important to know from a software development perspective about this topic and its relationship with traditional operating systems? How does ...

Explanation:

For each row in the picture, you have to switch on some of the bits to create the number on the left.

Each bit has a value, a "weight" so to speak. By switching on the bit, you add that weight to the sum.

These "weights" are shown at the top row.

So to create 4, it's easy, you just switch on the '4' bit.

Same for 128, only one bit has to be switched on.

40 is a bit more involved, now you have to switch on 32 and 8, since 32+8 is 40.

For every number, there is exactly one combination of switched on bits to create that number. In the case of 40, the binary representation is:

00101000.

Answer:

B, C, B

Explanation:

According to my understanding of these questions, these are in Java.

For the first one, there is a built in function called .length() for a string, so it's answer B.

For the second one, this should come out as C, 0 since compareTo compares the ascii values of the characters.

The third one's answer should be B. s1.equals(s2) for characters that are caps and not caps comes out with false, so ! would negate it. s1.equalsIgnoreCase(s2) would come out as true, ignoring the cases of APPLE.
