Rotate Vector Without Libraries | Dataford Interview Questions

Rotate a vector without using any library functions

Implement def rotate_vector(nums, k): to rotate the vector to the right by k positions in place and return it. Do not use built-in rotation, slicing, or reverse functions. If k exceeds the vector length, reduce it modulo the length.

Input is a non-empty list of integers and a non-negative integer k. Return the same list object after rotation.

Constraints

1 <= nums.length <= 10^4
-10^9 <= nums[i] <= 10^9
0 <= k <= 10^9
The vector must be modified in place
Do not use slicing, built-in reverse functions, or library rotation functions

Function Signature

def rotate_vector(nums, k):
