Given an integer x, find the square root of x. If x is not a perfect square, then return floor(√x).
x = 5
Explanation: Since, 5 is not a perfect
square, floor of square_root of 5 is 2.
x = 4
Explanation: Since, 4 is a perfect
square, so its square root is 2.
You don't need to read input or print anything. The task is to complete the function floorSqrt() which takes x as the input parameter and return its square root. Note: Try Solving the question without using sqrt Function.
