Solution: Rotate Array

Explore how to rotate an integer array by k positions to the right using an in-place approach. Understand how reversing segments of the array with two pointers achieves the desired rotation efficiently, without extra space. This lesson teaches you the step-by-step process, code implementation, and analyzes time and space complexities for optimal array manipulation.

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 ...
