  Easy
  
  URL: https://leetcode.com/problems/sqrtx/
  
  Implement int sqrt(int x).
  
  Compute and return the square root of x, where x is guaranteed to be a 
  non-negative integer.
  
  Since the return type is an integer, the decimal digits are truncated and 
  only the integer part of the result is returned.
  
  Example 1:
  Input: 4
  Output: 2
  
  Example 2:
  Input: 8
  Output: 2
  Explanation: The square root of 8 is 2.82842..., and since 
               the decimal part is truncated, 2 is returned.
