最后两个测试点没过

bool cmp(xin z,xin c){
    if(z.y<c.y) return 1;
     if(z.y>c.y) return 0;
     if(z.y==c.y){
        if(z.m<c.m) return 1;
         if(z.m>c.m) return 0;
         if(z.m==c.m){
            if(z.d<c.m) return 1;
            if(z.d>c.d) return 0;
            if(z.d==c.d){
                if(z.id>c.id) return 1;
                else return 0;
            }
        }
    } 
}

检查 return

@morning_hope

if(z.d<c.m) return 1;

=>

if(z.d<c.d) return 1;
