Solution: Rotate Array

Discover how to rotate an integer array to the right by k positions using an in-place method that leverages the two pointers technique. This lesson helps you understand the step-by-step reversal approach to reorganize array elements efficiently without extra memory, preparing you for similar coding interview challenges.

Statement

Given an integer array, nums, shift its elements to the right by k positions. In other words, rotate the array to the right by k steps, where k is non-negative.

Constraints:

  • 11 \leq nums.length 103\leq 10^3

  • 231-2^{-31} \leq ...
