题目:点击打开链接 题意:每个格子有不同颜色的气球用不同数字表示,每次可选某一行              或某一列来戳气球.每个人有K次机会.求最后哪些气球不能在             k次机会内被戳破.将这些气球的编号按升序输出. 分析:行列匹配,每种颜色的气球都要判断,故dfs传参时加一个气球的              编号. 感想:1.开始以为要按照最大匹配数按升序排列,昨天wa了一下午,把我搞郁闷了.                     今天重新看题,是要按照id来排序.  …
http://acm.hdu.edu.cn/showproblem.php?pid=1498 题意:给出一个 n*n 的矩阵,里面的数字代表一种颜色,每次能炸掉一排或者一列的相同颜色的气球,问有哪些颜色的气球不能在 k 次内炸完的,从小到大输出,能炸完输出-1. 思路:先存下点,用一个数字标记颜色是否出现过,然后遍历每一种颜色,再把这种颜色的行号和列号连边,跑一遍匈牙利,如果得到的结果大于 k 那么这种颜色就不行. #include <cstdio> #include <cstring&…
给一个矩阵,里面有一些不同颜色的气球.每次能够消灭一行或一列中某一种颜色的气球,问你在k次及以内,有哪些颜色的气球是不管怎样也消不完的. 那么思路就是,对每一种颜色的气球求最小点覆盖.>k 则为答案. 相当于 poj3041的加强版,由于矩阵中不是每个点都是等价的. #include<cstdio> #include<cstring> #include<cmath> #include<iostream> #include<algorithm>…
