Solution: Rotate Array

Explore how to rotate an integer array right by k positions using an in-place approach based on reversing segments with the two pointers technique. Understand the step-by-step process, time and space complexity, and gain skills to solve array rotation problems efficiently without extra memory.

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 ...
