Sqrt(x).js

/*Implement int sqrt(int x).

Compute and return the square root of x.

x is guaranteed to be a non-negative integer.


Example 1:

Input: 4
Output: 2
Example 2:

Input: 8
Output: 2
Explanation: The square root of 8 is 2.82842..., and since we want to return an integer, the decimal part will be truncated.*/
