Search in Rotated Sorted Array

Understand how to locate a target value within a rotated sorted integer array using a modified binary search approach. Learn to identify the correct index efficiently even when the array has been shifted by an unknown number of positions. Practice problem-solving skills with constraints such as unique values and ascending order, preparing you for similar coding interview questions.

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
