题意：最初，盒子是空的。你可以放一些细菌进去。每个细菌每晚会分裂成两个（2变4，4变8）。你需要在某一时刻，观察到X个细菌，请问至少投放多少个细菌。 题解：观察这道题，有二进制特征，应该想到位运算。 int main() { int n,ans=0; cin >> n; while (n) { if (n & 1) { ans++;//如果某一
Phoenix has decided to become a scientist! He is currently investigating the growth of bacteria. Initially, on day 11, there is one bacterium with mass 11. Every day, some number of bacteria will split (possibly zero or all). When a bacterium of mass mm s

You may be familiar with the idea that your gut and skin are home to a collection of microbes—fungi, bacteria and viruses—that are vital for keeping you healthy. But did you know that your eyes also host a unique menagerie of microbes? Together, they’re c
题意： 给你一个整数n(可能为负数),让你求满足a^p=n的最大的p 思路： 当n是正数时,直接对n进行素因子分解，在对它的素因子的个数进行gcd,比如12=2^2*3,gcd(2,1)就是最大的p; 当n是负数时,则p的值一定是奇数,因为一个数的偶数次方一定为整数，因此需要将它的素因子个数全都化为奇数。
分解质因数,求每个数指数,指数的gcd即是最大的p #include<bits/stdc++.h> using namespace std; #define fst first #define sec second #define sci(num) scanf("%d",&num) #define scl(num) scanf("%lld",&num) #define mem(a,b) memset(a,b,sizeof a) #defi
