题意:田忌赛马,每胜一局就得200,负一局少200,问最多得多少钱. 析:贪心,如果最快的马比齐王的还快,就干掉它,如果最慢的马比齐王的马快,就干掉它,否则用最慢的马去和齐王最快的马比. 代码如下: #pragma comment(linker, "/STACK:1024000000,1024000000") #include <cstdio> #include <string> #include <cstdlib> #include <cma…

题目来源:1052 题目分析:题目说的权值匹配算法,有点误导作用,这道题实际是用贪心来做的. 主要就是规则的设定: 1.田忌最慢的马比国王最慢的马快,就赢一场 2.如果田忌最慢的马比国王最慢的马慢,就让这两匹马比一场,输一场 3.如果田忌最慢的马和国王最慢的马相等,就看 如果田忌最快的马比国王最快的马快,那就比一场,赢 如果田忌最快的马比国王最快的马慢,就让最慢的马和国王最快的马比一场,这一场输 如果田忌最快的马和国王最快的马相等,就看田忌最慢的马是否比国王最快的马慢,如果是,输一场,否则就是所…
