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.

C++代码如下：

class Solution {
public:
int mySqrt(int x) {
  double s;
  s=sqrt(x);
  return int(s);
}
};
