Binary search 2d array c++
WebBinary search is an algorithm used to search for an element in a sorted array. In this algorithm the targeted element is compared with middle element. If both elements are equal then position of middle element is returned and hence targeted element is found. WebSep 22, 2024 · The brute force is a naive solution, but works on for this problem. Binary Search Sorting makes it possible to do binary search. This can be solved in two steps, first we binary search to find the target row index, and second, we find the target in the target row. The complexity is O (logM + logN).
