Problem: Rotate Array

Medium
30 min
Explore how to rotate elements of an integer array by k positions to the right using two-pointer methods. This lesson helps you understand problem constraints and implement solutions efficiently, preparing you for typical coding interview questions involving 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 nums[i] 23112^{31} - 1

  • 00 \leq k 103\leq 10^3
