题目连接:uva 10905 Children's Game 题目大意:给出n个数字, 找出一个序列,使得连续的数字组成的数值最大. 解题思路:排序,很容易想到将数值大的放在前面,数值小的放在后面.可是,该怎么判断数值的大小(判断数值大小不能单单比较两个数的大小,比如遇到:1 .10的情况).其实,判断一个不行,那就将两个合在一起考虑就可以了(就是比较110合101的大小来普判断1 放前面还是10放前面). #include <stdio.h> #include <string.h>…

题意:给出N个数,要求把它们拼凑起来,让得到的数值是最大的. 只要分别比较两个数放前与放后的值的大小,排序后输出就可以了. 比如123和56,就比较12356和56123的大小就行了. 写一个比较函数,然后用sort调用就行了. 刚开始时用long long做,每次比较都让数相连,然后比较大小,后来发现数据好像会很暴力,即使longlong也不够大. 考虑到两个数相连后两种情况长度都一样,所以只要把数值当成string来做就行了,比较两个string的字典序大小. 代码: /* * Author…

注意!这不是单纯的字典序排序,比如90.9,应该是990最大 对字符串排序蛋疼了好久,因为别人说string很慢,所以一直没有用过. 看别人用string还是比较方便的,学习一下 对了,这里的cmp函数写的还是很简洁的,比我写的要好得多 #define LOCAL #include <iostream> #include <cstdio> #include <cstring> #include <algorithm> using namespace std;…

题目 https://uva.onlinejudge.org/index.php?option=com_onlinejudge&Itemid=8&page=show_problem&problem=1846 题意 n个数字按照字符串方式直接组合成大数字,问最大组合成多少 思路 排序 感想 1. 因为脑洞的原因以为只要把所有数的数位填到一样长就好了,比如27,273,72,723把27填到272,72填到727,就能把它们顺利排出来.结果这样无法区别345, 3453这种情况和543…

贪心,假如任意给出一个序列,如果两两交换了以后会变大,那么就交换,直到不能交换为止. #include<bits/stdc++.h> using namespace std; ; string s[maxn]; int rk[maxn]; bool cmp(int x,int y) { , j = , n1 = s[x].size(), n2 = s[y].size(); string *s1 = &s[x], *s2 = &s[y]; int ct = n1+n2; whil…
