题目的意思是: 给你一个大数,然后删减其中的K个数,并且剩下的数还是按原来在的先后次序排列,求所得的那个数最小的那个数. 思路:贪心(要取得数最小,你从左往右选数的时候,选的第一数,就是选后组成数的位权最高的,要一个数最小,位权最高的所对应那位要最小,然后依次是下一位权最小).原来有N个数,删除K个数得最小数可以转化为从左往右选N-K个数所组成的数最小.那么第一个数必须在区间[0,K](数组下标)(存大数的数组首位是从0开始的). 证:选的第一位数如果超过K,假如取的是K+S(K+S<=N-1)…

题目链接:hdu 3183 A Magic Lamp 题目大意:给定一个字符串,然后最多删除K个.使得剩下的组成的数值最小. 解题思路:问题等价与取N-M个数.每次取的时候保证后面能取的个数足够,而且取的数最小,查询最小的操作用RMQ优化. #include <cstdio> #include <cstring> #include <algorithm> using namespace std; const int maxn = 10005; int N, M, d[m…
