Search in Rotated Sorted Array

Explore how to solve the problem of searching a target value in a rotated sorted array using modified binary search. Learn to handle unique constraints and implement a practical solution that returns the correct index or -1 if the target is not found. This lesson guides you through understanding problem requirements and coding an efficient search algorithm.

Statement

You are given a sorted integer array, nums, and an integer, target. The array may have been rotated by an arbitrary number. Your task is to find and return the index of target in this array. If target does not exist, return -1.

An original sorted array before rotation is given below:

g array 1 10 20 47 59 63 75 88 99 107 120 133 155 162 176 188 199 200 210 222
