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…

木棒 Time Limit: 1000MS Memory Limit: 10000K Total Submissions: 118943 Accepted: 27429 Description 乔治拿来一组等长的木棒.将它们随机地砍断.使得每一节木棍的长度都不超过50个长度单位.然后他又想把这些木棍恢复到为裁截前的状态,但忘记了初始时有多少木棒以及木棒的初始长度.请你设计一个程序,帮助乔治计算木棒的可能最小长度.每一节木棍的长度都用大于零的整数表示. Input 输入包括多组数据,每组数据包括两…

这题听说是道十分经典的剪枝算的题目,不要问我剪枝是什么,我也不知道,反正我只知道用到了深度搜索 我参考了好多资料才悟懂,然后我发现网上的那些大神原理讲的很明白,但代码没多少注释,看的很懵X,于是我抄起VS写了个详细注释版,真的很详细,史上最详细,全宇宙最详细,就这么自信,不信你看,看不懂你咬我. /*-------------------------------------------- * 剪枝算法经典例题Sticks详细注释版 *-------------------------------…

//这题又折腾了两天 心好累 //poj.hdu数据极弱,找虐请上uvalive 题意:给出n个数,将其分为任意份,每份里的数字和为同一个值.求每份里数字和可能的最小值. 解法:dfs+剪枝 1.按降序排序,长的木棍应该优先被使用 2.一个木棍一旦确定就不应当改变,因为新得到的木棍不会更优 3.如果当前循环扫到的第一根木棍加不进去直接return false 因为可以在后面的循环里被搜到 4.如果前一根等长的没有被使用那么不进入循环 5.份数要能整除总长度才会检查是否为合法解 #include<…
