Given an integer x, find the square root of x. If x is not a perfect square, then return floor(√x).
Example 1:
Input:
x = 5
Output: 2
Explanation: Since, 5 is not a perfect
square, floor of square_root of 5 is 2.
Example 2:
Input:
x = 4
Output: 2
Explanation: Since, 4 is a perfect
square, so its square root is 2.
Your Task:
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 the sqrt function. The value of x>=0.
Expected Time Complexity: O(log N) Expected Auxiliary Space: O(1)

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
On submission, your code is tested against multiple test cases consisting of all
possible corner cases and stress constraints.
