Sticks Problem Description George took sticks of the same length and cut them randomly until all parts became at most 50 units long. Now he wants to return sticks to the original state, but he forgot how many sticks he had originally and how long the…
题目大意: George有许多长度相同的木棍,随机的将这些木棍砍成小木条,每个小木条的长度都是整数单位(长度区间[1, 50]).现在George又想把这些小木棒拼接成原始的状态,但是他忘记了原来他有多少根木棍,也忘记了木棍的长度.现在请你编写一个程序,找到最短的原始的木棍长度. 输入: 每个测试案例包含两行,第一行表示小木条的总个数(最多64根小木条),第二行表示每个小木条的长度,用空格分开.当第一行输入为零的时候表示程序结束. 输出: 对于每个测试案例输出最短的木棍长度. 解题思路: 用搜索…
题目大意: 给你一个总和(total)和一列(list)整数,共n个整数,要求用这些整数相加,使相加的结果等于total,找出所有不相同的拼凑方法. 例如,total = 4,n = 6,list = [4,3,2,2,1,1]. 有四种不同的方法使得它们相加的结果等于total(即等于4),分别为:4,3+1,2+2, 2+1+1. 在同一种拼凑方式中,每个数字不能被重复使用,但是在list中可能存在许多相等的数字. 输入: 输入包含许多测试用例,每个用例仅占一行.每个用例包含t(total)…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=5543 题意:给你一根长为m的长木板和一些小木棒,每一根小木棒有它的长度和价值,这些小木棒要放在长木板上并且每一根小木棒的重心要在长木板上(即可以露出一半的长),问最大价值是多少. dp[i][j][k]  表示前i个小棒放到长度为j的木板上,其中有k个小棒放在边沿部分, 边沿部分的小棒需要尽量放在木板外面(贪心思维),所以放在边沿的木棒落在木板上的长度为l/2.然后就是简单的01背包问题了. tip…
