CodeForces - 892C 题目链接:http://codeforces.com/contest/892/problem/C 题目大意:让所有数都变成1的最少步数 解题思路:对于能出现gcd=1,那么就是使出现gcd=1的次数加上n-1,现在考虑如何用最少的步数求得gcd=1,因为对于a,b,c,d,e,先求得gcd(a,b),gcd(b,c),gcd(c,d),gcd(d,e),如果出现...
CodeForce-803C Maximal GCD(贪心数学) Maximal GCD CodeForces - 803C 现在给定一个正整数n。你需要找到k个严格递增的正整数a1, a2, ..., ak,满足他们的和等于n并且他们的最大公因数尽量大。 如果不可能请输出-1。 这k个数的gcd的必定是n的因数,于是变成枚举n的因数,可以知道只需要枚举 1~sqrt(...
HDU 2503 a/b + c/d(gcd问题) 技术标签: gcd题意很清楚,直接上代码。 AC代码: #include<stdio.h> int gcd(int a, int b){ //求最大公约数 int x; x = a % b; while(x != 0){ a = b; b = x; x = a % b; } return b; } int main(){ int n; scanf("%d", &n); ...
