WebShifted Array Search A sorted array of distinct integers shiftArr is shifted to the left by an unknown offset and you don’t have a pre-shifted copy of it. For instance, the sequence 1, 2, 3, 4, 5 becomes 3, 4, 5, 1, 2, after shifting it twice to the left. WebA simple solution would be to run a linear search on the array and find the minimum element index. The problem with this approach is that its worst-case time complexity is O(n), where n is the size of the input. This solution also does not take advantage of the fact that the input is circularly sorted.
