Rotated sorted array gfg
Did you know?
WebWe know that the middle element always divides the array into two subarrays, and the pivot element can lie only in one of these halves. It is worth noticing that at least one of these subarrays will always be sorted. If middle element happens to be the point of rotation (minimum element), then both left and right subarrays are sorted. WebFeb 27, 2024 · Approach: The idea is the same as the previous one without duplicates. The only difference is that due to the existence of duplicates, arr[low] == arr[mid] could be …

You need to find all pairs in the array that sum to a number K. If no such pair exists then output will be -1. The elements of the array are …
WebSuppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., [1, 4, 6, 8, 11, 13, 15] might become [8, 11, 13, 15, 1, 4, 6]). You are given a target value to search. If found in the array return its index, otherwise return -1. You may assume no duplicate exists in the array. Your algorithm's runtime complexity must be in … WebA sorted(in ascending order) array A[ ] with distinct elements is rotated at some unknown point, the task is to find the minimum element in it.
