Leetcode - Shift 2D Grid (Python)

[@janmichaelaustria620]

Woah you're back! I had no idea. Glad to see you're still doing the daily challenges when you can man! I did this slightly differently. Since k*rows*cols, was small i just swapped in place starting with the bottom right class Solution: def shiftGrid(self, grid: List[List[int]], k: int) -> List[List[int]]: rows = len(grid) cols = len(grid[0]) for _ in range(k): prev = grid[-1][-1] for row in range(rows): for col in range(cols): #save what is curretnly there temp = grid[row][col] grid[row][col] = prev prev = temp return grid swapping in place use modular arithmetic was pretty tricky! it took me to a bit to realize we swapped for every multiple of (j+ k) % N. we'd eventually hit the original i we started off with, which is why we advanced it i += 1
