at least put the problem link lol
Your full dp state is $$$[i,j,steps]$$$ but you are only memoizing $$$[i,j]$$$. You probably wanted your dp to be $$$dp[i][j]$$$ the least steps to go from $$$(i,j)$$$ to $$$(m-1,n-1)$$$. You calculate the transitions similarly for a total time of $$$O(mn(m+n))$$$ which is correct but too slow, so you'd need a way to calculate transitions faster.
