Question
Given an integer array nums and a positive integer k, reverse every consecutive block of k elements in place: the first k elements get reversed, then the next k, and so on. If fewer than k elements remain at the end, reverse that shorter block too. Return the array. Example: nums = [1, 2, 3, 4, 5], k = 2 gives [2, 1, 4, 3, 5] — and with k = 3 it gives [3, 2, 1, 5, 4].
reverse_blocks(nums: list[int], k: int) → list[int][[1,2,3,4,5],2]out[2,1,4,3,5]State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.
