WebMar 21, 2024 · Binary Search based problems: Find a peak element in a given array Check for Majority Element in a sorted array K-th Element of Two Sorted Arrays Find the number of zeroes Find the Rotation Count in Rotated Sorted array Find the point where a monotonically increasing function becomes positive first time Median of two sorted arrays 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.
