题目链接 Print Check 注意到行数加列数最大值只有几千,那么有效的操作数只有几千,那么把这些有效的操作求出来依次模拟就可以了. #include <bits/stdc++.h> using namespace std; #define rep(i,a,b) for(int i(a); i <= (b); ++i) + ; + ; struct node{ int op, x, y; } a[N]; int col[Q][Q]; int v[N]; //v[i] = 1 则第i个…

对于每一个格子,看是行最后画还是列最后画.预处理一下就可以了. #include<stdio.h> #include<string.h> int n,m,k; +]; +]; +]; +]; int main() { scanf("%d%d%d",&n,&m,&k); memset(high,-,sizeof high); ;i<=k;i++) scanf("%d%d%d",&op[i],&id[…

题意: 按顺序给定列和行进行涂色,输出最终得到的方格颜色分布. 分析: 记录下涂的次序,如果某个元素的横和列都被涂过,那么就选择次序最大的颜色. 代码: #include<iostream> #include<cstdio> using namespace std; const int maxn = 5005; int num[maxn][maxn]; int ma[2][maxn]; int ro[maxn], ca[maxn]; int main (void) { int n,…

连接:Print Check 题意:n行m列的矩阵,有k次涂色,每一涂一行或者一列,求最后的涂色结果. 从数据的大小看,暴力肯定要TLE: 问题是如何存储数据. 首先:我们只要最后的涂色结果. 其次:没有必要用for每个数据涂一遍. 所以如果能一次直接涂一行就可以了: #include <iostream> #include <cstdio> uising namespace std; #define N 5005 ; typedef long long LL; int row[N…

注意到R和C只与最后一个状态有关 /*H E A D*/ struct node2{ int kind,las,val,pos; node2(){} node2(int k,int l,int v,int p){ kind=k;las=l; val=v;pos=p; } }b[maxn]; bool cmp(node2 a,node2 b){ return a.las<b.las; } int mt[5003][5003]; int main(){ int n,m,k,op; while(~ii…
