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,…

生成函数题. 题意:有币值1,2,5的硬币若干,问你最小的不能组成的币值为多少. 解法:写出生成函数: 然后求每项的系数即可. 因为三种硬币最多1000枚,1*1000+2*1000+5*1000=8000,那么多项式乘积的最高次数为8000 用c保存累计相乘各项的系数,tc保存c和当前项相乘的系数 代码: #include <iostream> #include <cstdio> #include <cstring> #include <cmath> us…

题目:http://acm.hdu.edu.cn/showproblem.php?pid=1085 可以这样理解题意:给出1元,2元和5元的三种硬币若干,每种硬币数量给出,现在可以从所有的硬币中,选出若干(三种中的若干种,若干个)组合出一定的金额,待求的是不能组合出来的金额的最小值. 例如 题目给出的测试例题中,三种硬币数量分别为1,1,3,则题目抽象成数学问题为: (1+x)(1+x^2)(1+x^5+x^10+x^15)的乘积展开式中,按照次数递增的顺序排列,第一个系数为0的项的次数是多少次…

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…
