菜鸟级DP,贴代码#include <cstdio>
#include <algorithm>
using namespace std;
const int MAX_N = 350;
int main() {
int dp[MAX_N][MAX_N];
int n;
/*input*/
scanf("%d", &n);
for(int i = 0;i<n;i++){
for(int j = 0;j<=i;j++)
scanf("%d", &dp[i][j]);
}
/*input*/
/*dp*/
for(int i = n-2; i>= 0 ;i--)
for(int j = i; j>=0 ; j--)
dp[i][j] += max(dp[i+1][j], dp[i+1][j+1]);
printf("%d", dp[0][0]);
return 0;
}
