Implementint sqrt(int x).
Compute and return the square rootX.
Note ]:
1. Int type may overflow, so multiplication is not allowed. Try to use division.
2. The vast majority of numbers are not open-ended. How can we get close

Q:Implement int sqrt (int x).Compute and return the square root of X.A:Here are two methods of implementation: One is binary search, the other is Newton iterative method.1.Two-point searchFor a non-negative n, its square root is no greater than (n/2+
Implement int sqrt(int x) .Compute and return the square root of x, where x is guaranteed to bes a non-negative integer.Since The return type is a integer, the decimal digits is truncated and only the integer part of the result is returned.Example 1:
