/**

* @author yangchd 2018/10/24

*

* 69.Sqrt(x)

* 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.
