思路
六年级记忆,但是这道题更简单一些,动物越多也就是鸡尽量多就好了,动物越少也就是兔子尽量多就好了。但是总脚数肯定是偶数。
#include <iostream> #include <vector> using namespace std; int main(){ int a, minNum, maxNum; while(cin >> a){ minNum = maxNum = 0; if(a % 2 == 0){ int rabbit = a / 4; minNum = rabbit + (a - rabbit * 4) / 2; maxNum = a / 2; } cout << minNum << " " << maxNum << endl; } return 0; }
