Swap Two Numbers Problem Statement

Given two integers a and b, your task is to swap these numbers and output the swapped values.

Input:

The first line contains a single integer 't', representing the number of test cases. Each subsequent line contains two space-separated integers, 'a' and 'b'.

Output:

For each test case, output the swapped values in a single line as 'b' followed by 'a'.

Example:

Input: 2 3 4 5 6 Output: 4 3 6 5

Constraints:

1

Swap Two Numbers Problem Statement

Given two integers a and b, your task is to swap these numbers and output the swapped values.

Input:

The first line contains a single integer 't', representing the number of test cases.
Each subsequent line contains two space-separated integers, 'a' and 'b'.

Output:

For each test case, output the swapped values in a single line as 'b' followed by 'a'.

Example:

Input:
2
3 4
5 6
Output:
4 3
6 5

Constraints:

1 <= 't' <= 10²
-10⁵ <= 'a', 'b' <= 10⁵
Time Limit: 1 sec

Note:

You do not need to print anything; it has already been taken care of. Just implement the specified function to return the results.

Accepted Answer

Swap two numbers 'a' and 'b' and output the swapped values.

Create a temporary variable to store one of the numbers
Assign the value of 'a' to 'b' and the temporary variable to 'a'
Output the swapped values as 'b' followed by 'a'

Accepted Answer

function swap(a, b){
     const temp = a;
     a = b; b = temp;
     return [a, b]
}
