//////////////////////////////////////////////Sqrt(x)/////////////////////////////////////////////////////
// Given a non-negative integer x, compute and return the square root of x.
// Since the return type is an integer, the decimal digits are truncated, and only the integer part of the result is returned.
// Note: You are not allowed to use any built-in exponent function or operator, such as pow(x, 0.5) or x ** 0.5.
// Example 1:
//
// Input: x = 4
// Output: 2
// Example 2:
//
// Input: x = 8
// Output: 2
// Explanation: The square root of 8 is 2.82842..., and since the decimal part is truncated, 2 is returned.
const mySqrt = function(x) {
    return Math.sqrt(x).toString().split('.')[0];
};

// console.log(mySqrt(4));
// console.log(mySqrt(8));
