Search in Rotated Sorted Array

Explore methods to locate a target integer in a rotated sorted array by understanding the underlying problem and applying modified binary search strategies. This lesson guides you through identifying the target's index efficiently or returning -1 if it doesn't exist, enhancing your problem-solving skills for coding interviews.

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
