#include<stdio.h> int main() { int n,m,k,r,b,y; scanf("%d%d%d",&n,&m,&k); r=(n+k-m)/2; b=n-r; y=k-r; printf("red:%d blue:%d yellow:%d\n",r,b,y); return 0; }
C++解答
#include<iostream> using namespace std; int main() { int a,b,c,s,e,d; cin>>a>>b>>c; if (a>b) { s=(c+(a-b))/2; e=a-s; d=b-e; cout<<"red"<<":"<<s<<" "<<"blue"<<":"<<e<<" "<<"yellow"<<":"<<d<<endl; } else if (b>a) { s=(c+(b-a))/2; e=b-s; d=a-e; cout<<"red"<<":"<<d<<" "<<"blue"<<":"<<e<<" "<<"yellow"<<":"<<s<<endl; } return 0; }
