Rotated Array

Suppose a sorted 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).

Find the minimum element.

The array will not contain duplicates.

  • NOTE 1: Also think about the case when there are duplicates. Does your current solution work? How does the time complexity change?*


Note: If you know the number of times the array is rotated, then this problem becomes trivial. If the number of rotation is x, then minimum element is A[x].
Lets look at how we can calculate the number of times the array is rotated.

Complete solution in the hints.

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.
