Swap Two Numbers
Posted: 27 Jan, 2021
Take two numbers as input and swap them and print the swapped values.
The first line of input contains a single integer 't', representing the total number of test cases. The second line of input contains two integers 'a' and 'b', representing the second number.
The first line of output prints the swapped value of 'a' and 'b'.
You do not need to print anything, it has already been taken care of. Just implement the given function.
1 <= 'T' <= 10^2 -10^5 <= 'a', 'b' <= 10 ^ 5 Time Limit: 1 sec
