Показать описание
Leetcode 189 Rotate Array. Python based optimized solution with clear explanation.
In LeetCode problem 189, One common approach to solve LeetCode problem 189 involves using the concept of cyclic rotations. After calculating the effective number of rotations (taking modulo with the length of the array). Reverse the first k elements and the remaining n-k elements then you can reverse the entire array separately to achieve the desired rotation in-place. This approach ensures a time complexity of O(n) and constant space complexity.
