如何控制代码长度为256B

#include<iostream>
int a[1001][1001],dp[1001][1001],n,r;int main(){scanf("%d",&n);while(n--){int ans=0;scanf("%d",&r);for(int i=1;i<=r;i++)for(int j=1;j<=i;j++)scanf("%d",&a[i][j]);for(int i=1;i<=r;i++)for(int j=1;j<=i;j++){dp[i][j]=a[i][j]+max(dp[i-1][j-1],dp[i-1][j]);ans=max(ans,dp[i][j]);}printf("%d\n",ans);}return 0;}
