Challenge 2: Search in a Rotated Array
Let's write a function to search in a sorted and rotated array
We'll cover the following
Problem Statement
Given a sorted array of n
integers that has been right rotated an unknown number of times, write code to find an element in the array. You may assume that the array was originally sorted in ascending order.
Input
A sorted array that has been rotated a number of times
Output
The index of the element
Sample Input
int arr[] = {7, 8, 9, 0, 3, 5, 6}
int left = 0; // Index of the start of the array
int right = 6; // Index of the end of the array
int s = 3; // Element that is being searched for
Sample Output
4 // Index of the element that was searched for
