Integer Square Root Calculation

Given a positive integer 'N', compute its square root and return it. If 'N' is not a perfect square, then return the floor value of sqrt(N).

Example:

Input:

N = 25
N = 20
N = 2

Output:

5
4
1

Explanation:

For 'N' = 25, the output is 5 as 5*5 = 25. For 'N' = 20, the output is 4 because the floor value of the square root of 20 is 4. Similarly, for 'N' = 2, the floor value of the square root is 1.

Accepted Answer

Calculate the square root of a positive integer and return the floor value if not a perfect square.

Use the sqrt() function to calculate the square root of the given integer.
If the square root is not an integer, return the floor value using floor() function.
Handle constraints such as the range of 'N' and the number of test cases.
