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.

"WebWhen we binary search on an answer, we start with a search space of size N N which we know the answer lies in. Then each iteration of the binary search cuts the search space in half, so the algorithm tests \mathcal {O} (\log N) O(logN) values. This is efficient and much better than testing each possible value in the search space. " - C++ std binary search
