可能有点长,不是最优解
#include<bits/stdc++.h> using namespace std; int main(){ int x,y,b; cin>>x>>y; if(y<=0 || y>12) cout<<"no answer"; if(x%400==0) b=1; else if(x%100==0) b=0; else if(x%4==0) b=1; else b=0; if(b==1) { if(y==1 || y==3 || y==5 || y==7 || y==8 || y==10 ||y==12) cout<<"31"; else if(y==4 || y==6 || y==9 || y==11 ) cout<<"30"; else if(y==2) cout<<"29"; } if(b==0) { if(y==1 || y==3 || y==5 || y==7 || y==8 || y==10 ||y==12) cout<<"31"; else if(y==4 || y==6 || y==9 || y==11 ) cout<<"30"; else if(y==2) cout<<"28"; } return 0; }

懒人代码
#include<bits/stdc++.h> using namespace std; const int INF=0x3f3f3f3f; int const N=1e5+10; int x,y; int main(){ cin>>x>>y; if(y==2){ if(x%4==0&&x%100!=0||x%400==0){ cout<<29; return 0; }else{ cout<<28; return 0; } } if(y==1||y==3||y==5||y==7||y==8||y==10||y==12)cout<<31; else{ cout<<30; } return 0; }

} //这是绝对AC的代码,并且怎样测试都不会出错(2000年 3月出现的是31)
