题意: 有面值分别为1.2.5的硬币,分别有num_1.num_2.num_5个,问不能组成的最小面值是多少?(0<=每种硬币个数<=1000,组成的面值>0) 思路: 母函数解决.只有3个括号要作乘法,分别代表面值1.2.5所能组成的情况.需要两个数组,所能组成的最大值为num_1+2*num_2+5*num_5.如果在这个范围内都能组成,那么最小不能组成的面值为num_1+2*num_2+5*num_5+1.若没有1分钱的硬币,那么不能组成的肯定是1了. 数组的用法:ans[]保存第…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1085 解题报告:有1,2,5三种面值的硬币,这三种硬币的数量分别是num_1,num_2,num_5,问你不能凑的钱的最小值是多少. DP,开一个这样的数组dp[i][3],然后dp[i][0]表示凑成 i 元钱需要dp[i][0]张1块的,需要dp[i][1]张两块的,dp[i][2]张5块的,然后依次往后递推,得到 i 的途径一共有三种,第一种是i-1加一张一块的,第二种是i-2加上1张两块的,…
