Rotated-Sorted-Array

Problem There is an integer array nums sorted in non-decreasing order (not necessarily with distinct values). Before being passed to your function, nums is rotated at an unknown pivot index k (0 <= k < nums.length) such that the resulting array is [nums[k], nums[k+1], ..., nums[n-1], nums[0], nums[1], ..., nums[k-1]] (0-indexed). For example, [0,1,2,4,4,4,5,6,6,7] might be rotated at pivot index 5 and become [4,5,6,6,7,0,1,2,4,4]. Given the array nums after the rotation and an integer target, return true if target is in nums, or false if it is not in nums. ...

Problem Question : Find the minimum element in the rotated sorted array. Example Example 1: Input: nums = [5, 7, 9, 1, 3] Output: 3 Explanation: The original array was [1, 3, 5, 7, 9] rotated 3 times. ...

Problem Find the minimum element in the rotated sorted array. For example, the array a = [0, 1, 2, 4, 6, 8, 10] might become: [8, 10, 0, 1, 2, 4, 6] if it was rotated 2 times. [4, 6, 8, 10, 0, 1, 2] if it was rotated 4 times. Notice that rotating an array [a[0], a[1], a[2], ..., a[n-1]] 1 time results in the array [a[n-1], a[0], a[1], a[2], ..., a[n-2]]. ...

Problem Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., [0, 1, 2, 4, 5, 6, 7] might become [4, 5, 6, 7, 0, 1, 2]). 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. Follow up: what if duplicates are allowed? ...
