Given an array of integers A of size N and an integer B.
array A 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 B to search. If found in the array, return its index, otherwise return -1.
You may assume no duplicate exists in the array.
NOTE:- Array A was sorted in non-decreasing order before rotation.
- NOTE : Think about the case when there are duplicates. Does your current solution work? How does the time complexity change?*
The first argument given is the integer array A. The second argument given is the integer B.
Return index of B in array A, otherwise return -1
1 <= N <= 1000000 1 <= A[i] <= 10^9 all elements in A are disitinct.
Input 1: A = [4, 5, 6, 7, 0, 1, 2, 3] B = 4 Output 1: 0 Explanation 1: Target 4 is found at index 0 in A. Input 2: A = [5, 17, 100, 3] B = 6 Output 2: -1
NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a doubt? Checkout Sample Codes for more details.
