Dec 18, 2019 · My solution actually takes less than 1 ms, the other ~35 ms are LeetCode's overhead and variation. So let's subtract 35 ms as baseline. mine takes about 0.533 ms (= (568 - 35) / 1000). yours takes about 14.96 ms (= (1531 - 35) / 100). mine2 takes about 3.3 ms (= (365 - 35) / 100). So, yes, that optimization makes it much slower.
The distance used in this problem is the Manhattan distance: the distance between two cells (x0, y0) and (x1, y1) is |x0 - x1| + |y0 - y1| . Example 1: Input: ...
