首先计算图的联通情况,如果图本身不联通一定不会出现生成树,输出"NO",之后清空,加白边,看最多能加多少条,清空,加黑边,看能加多少条,即可得白边的最大值与最小值,之后判断Fibonacci数是否在这两个之间,如果是输出yes,否则no. 然而,,然而,,我看的题解有问题!!!!!调了俩小时愣是没找出错误来,,然后把题解交了发现过不了,,,,真是够了.,.,., 第二天上午终于A了,,满分程序: #include <cstdio> #include <cstring&…

一个由n个顶点m条边(可能有重边)构成的无向图(可能不连通),每条边的权值不是0就是1. 给出n.m和每条边的权值,问是否存在生成树,其边权值和为fibonacci数集合{1,2,3,5,8...}中的一个. 求最小生成树和最大生成树,得到生成树边权和的下界left和上界right.这道题由于每条边权值不是0就是1,因此生成树边权和可以覆盖到[left,right]的每一个数.那么求得[left,right],看是否有fibonacci数在区间内就可以了. #include <cstdio>…

题目链接: hdu: http://acm.hdu.edu.cn/showproblem.php?pid=5167 题意: 给你一个x,判断x能不能由斐波那契数列中的数相乘得到(一个数可以重复使用) 题解: 1.筛法 首先,小于10^9的斐波那契数很少,就42个(不包括0,1),对于给定的x能同时成为它的因子的斐波那契数更少,所以可以暴力考虑所有能整除x的斐波那契数组成的集合的所有子集. 但是,对于每个子集做筛法的时候必须从大的数开始筛(质因数分解可以随便筛是因为一个数的质因数分解具有唯一性,但…
