WebApr 9, 2024 · Binary search. Greedy. Binary search. Using the binary search is not trivial, as usually the binary search has to have a continuous searching space. It means if we have a vaild region, such as [low, high], then all the continuous values between low and high must be valid. For this problem, it is continuous as shown in below example: 1, 2, 2, … WebAt each step of Binary Search, we reduce the potential size of the array by half where the target element can be found. Due to this, the function to search using binary search can apply the function recursively on a smaller part of the array.

Constraints: 1 <= N <= 105 1 <= arr [i] <= 106 1 <= K <= 106 WebFollowing is an iterative implementation of the bubble sort algorithm in C, Java, and Python. The implementation can be easily optimized by observing that the n'th pass finds the n'th largest element and puts it in its final place. So, the inner loop can avoid looking at the last n-1 items when running for the n'th time. WebApr 16, 2024 · We have discussed the binary search and it’s algorithm.
