Statement
You are required to find an integer value target
in an array arr
of non-distinct integers. Before being passed as input to your search function, arr
has been processed as follows:
It has been sorted in non-descending order.
It has been rotated around some pivot
, such that, after rotation, it looks like this: [nums[k], nums[k+1], ..., nums[n-1], nums[0], nums[1], ..., nums[k-1]]
. For example,[10, 30, 40, 42, 42, 47, 78, 90, 901]
, rotated around pivotbecomes [47, 78, 90, 901, 10, 30, 40, 42, 42]
.
Return TRUE if t
exists in the rotated, sorted array arr
, and FALSE otherwise, while minimizing the number of operations in the search.
Note: In this problem, the value of
is not passed to your search function.
