Binary search for loop python

WebJul 27, 2024 · In a binary search algorithm, the array taken gets divided by half at every iteration. If n is the length of the array at the first iteration, then at the second iteration, the length of the array will be n/2. Again dividing by half in the third iteration will make the array’s length = (n/2)/2=n/ (2^k). WebAug 18, 2024 · In python, we can implement the Binary Search algorithm in two ways.
