终于，终于（激动），终于做出来辣！！！！！！！！！！！！！！！！！！！！！ 真的太复杂啦：

ll x1,y1,x2,y2,c;
	while(p--){
		scanf("%lld %lld %lld %lld %lld",&x1,&y1,&x2,&y2,&c);
		b[x1][y1]+=c;//利用差分快速加法
		b[x1][y2+1]-=c;
		b[x2+1][y1]-=c;
		b[x2+1][y2+1]+=c;
	}
	for(int i=1;i<=n;i++){//构造加法后的a数组
		for(int j=1;j<=m;j++){
			b[i][j]+=b[i-1][j]+b[i][j-1]-b[i-1][j-1];
			printf("%lld ",b[i][j]);
		}
		printf("\n");
	}
	for(int i=1;i<=n;i++)//再构造a的前缀和数组

		printf("%lld\n",sum);
