+ * Given an integer x, find the square root of x. If x is not a perfect square, then return floor(√x).
+ * <p>
+ * For example,
+ * if x = 5, The answer should be 2 which is the floor value of √5.
+ * <p>
+ * The approach that will be used for solving the above problem is not going to be a straight forward Math.sqrt().
+ * Instead we will be using Binary Search to find the square root of a number in the most optimised way.
