WebSep 18, 2024 · Approach : 1) As the square root of number lies in range 0 <= squareRoot <= number, therefore, initialize start and end as : start = 0, end = number. 2) Compare the square of the mid integer with the given number. If it is equal to the number, the square root is found. Else look for the same in the left or right side depending upon the scenario.
