[LeetCode]#1030. Matrix Cells in Distance Order

Input: R = 1, C = 2, r0 = 0, c0 = 0
Output: [[0,0],[0,1]]
Explanation: The distances from (r0, c0) to other cells are: [0,1]
  1. Calculate distance and related coordinate.
  2. Sort it.
  3. Return it based on distance.
class Solution:
def allCellsDistOrder(self, R, C, r0, c0):
for i in range(R):
for j in range(C):
tmp.append((abs(r0 - i) + abs(c0 - j), [i, j]))
for i in range(len(tmp)):
return ans
