WebBinary Search Algorithm – Iterative and Recursive Implementation Given a sorted array of n integers and a target value, determine if the target exists in the array in logarithmic time using the binary search algorithm. If target exists in the array, print the index of it. For example, Input: nums [] = [2, 3, 5, 7, 9] target = 7 WebThe key idea is that when binary search makes an incorrect guess, the portion of the array that contains reasonable guesses is reduced by at least half. If the reasonable portion had 32 elements, then an incorrect guess cuts it down to have at most 16. Binary search halves the size of the reasonable portion upon every incorrect guess.
