DP problem (Top down vs bottom up)

Revision en1, by rr459595, 2019-06-26 17:28:25

I tried solving this problem on leetcode (https://leetcode.com/problems/dungeon-game/). I got AC with bottom up approach but wrong answer with top down approach.

Can someone help me in proving why only bottom up approach works?
