纯暴力解法，满足价钱100 数量也100即可

#include <iostream>
using namespace std;

int main() {
    int cock, hen, chick;
    for(cock = 0; cock <= 20; ++cock) {
        for(hen = 0; hen <= 34; ++hen) {
            for(chick = 0; chick <= 300; ++chick) {
                if(chick % 3) continue;
                if(5*cock + 3*hen + chick/3 == 100 && cock + hen + chick == 100) {
                    cout << cock << " " << hen << " " << chick << endl;
                }
            }
        }
    }
    return 0;
}
