Suppose a sorted array is rotated at some pivot unknown to you beforehand.
0 1 2 4 5 6 7 might become
4 5 6 7 0 1 2 ).
You are given a target value to search. If found in the array, return its index, otherwise return
You may assume no duplicate exists in the array.
Input : [4 5 6 7 0 1 2] and target = 4 Output : 0
- NOTE : Think about the case when there are duplicates. Does your current solution work? How does the time complexity change?*
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.
