Zeal Test Series 2019: Algorithms - Time Complexity
A sorted array of n elements which has been circularly shifted. For example, {18,25,1,5,11,16} is a sorted array that has been circularly shifted by 2 positions. suppose a person has to find the largest element in a circularly shifted array. Here, there ... been shifted is unknown. find time complexity. 1. O(nlogn) 2. O(n) 3. O(n^2) 4. O(logn)
