Finding the problem is the first task based on the input, output format and exe file provided. Then think the logic and code the same.
The task in this problem is to find the root mean square of the list of values provided.
• The first input is the number of test cases.
• Then the array is to be inputted and root mean square value is to be found.
• This can be done by first squaring all the values available, adding them and calculating the square root of the sum.
