10 30 -5 (P) This problem is two-dimensional dynamic programming, the key is the tectonic transfer equation. The first requirement for each step of the move process Knight HP is greater than 0, followed by the minimum requirements. So we can construct a matrix DP of MXN to record the moving process. Its transfer equation is Dp[row][col]=max (1,min (dp[row+1][col],dp[row][col+1])-dungeon[row][col]) space complex
