昨天这场CF打的还挺爽的,不过就是没咋涨Rating,没把握好涨Rating的机会。。
本来可以过四题的,,但是很失败,重评后跪了两道。。唉:-(
A. Vasya and Football
思路:给每个人计数,黄牌+1,红牌+2。
当数字第一次超过2时输出。
题目链接:A. Vasya and Football
AC代码:
#include#include #include #include #include #include using namespace std;struct node { char name[25]; int a[105];}home, away;int main(){ for(int i=0; i
B. Vasya and Wrestling
思路:先用sum是否为0判断分高的,sum>0 => first, sum second,
sum=0则相同,再判断字典序,如果再相同则判断最后一次动作。
注意sum需要long long。
题目链接:B. Vasya and Wrestling
AC代码:
#include#include #include #include #include #include using namespace std;int judge(int a[], int b[], int na, int nb){ int i, j; for(i=0, j=0; i b[i])return 1; else if(a[i]0)a[na++] = t; else if(t0)printf("first\n"); else if(sum0)printf("first\n"); else if(judge(a,b,na,nb)==2&&t
C. Vasya and Basketball
思路:给所有球排序,先把全部都赋值为3,然后依次减为2,再判断其中间过程的MAX
昨天做题的时候有点小混乱。。
题目链接:C. Vasya and Basketball
AC代码:
#include#include #include #include #include
D. Vasya and Chess
思路:貌似这题有点水。。
题目链接:D. Vasya and Chess
AC代码:
#include#include #include #include #include #include using namespace std;int main(){ int n; scanf("%d", &n); if(n%2==1) printf("black\n"); else if(n%2==0) { printf("white\n1 2\n"); } return 0;}
