Codeforces 697A - Pineapple Incident

题目链接:http://codeforces.com/problemset/problem/697/A

题目大意:

  输入三个数 t,s,x; 判断x是否合适

  合适的位置位 t , t+s, t+s+1, t+2s , t+2s+1 ,t+3s, t+3s+1 ......

  如果在合适的位置中,输出 “YES” 不合适输出“NO”

解题思路:

  如果x<t 不合适

  如果 (x-t)%s !=0|| !=1 合适 【注意要排除 x=t+1 这种情况】

AC Code :

 1 #include<stdio.h>
 2 int main()
 3 {
 4     int t,s,x,tem;
 5     while(~scanf("%d%d%d",&t,&s,&x))
 6     {
 7         tem=(x-t)%s;
 8         if(x<t||x==t+1||(tem!=0&&tem!=1))puts("NO");
 9         else puts("YES");
10     }
11     return 0;
12 }

【codeforces 718E】E. Matvey&#39;s Birthday

题目大意&链接: http://codeforces.com/problemset/problem/718/E 给一个长为n(n<=100 000)的只包含‘a’~‘h’8个字符的字符串s.两个位置i,j(i!=j)存在一条边,当且仅当|i-j|==1或s[i]==s[j].求这个无向图的直径,以及直径数量. 题解:  命题1:任意位置之间距离不会大于15. 证明:对于任意两个位置i,j之间,其所经过每种字符不会超过2个(因为相同字符会连边),所以i,j经过节点至多为16,也就意味着边数至多

Educational Codeforces Round 21 G. Anthem of Berland(dp+kmp)

题目链接:Educational Codeforces Round 21 G. Anthem of Berland 题意: 给你两个字符串,第一个字符串包含问号,问号可以变成任意字符串. 问你第一个字符串最多包含多少个第二个字符串. 题解: 考虑dp[i][j],表示当前考虑到第一个串的第i位,已经匹配到第二个字符串的第j位. 这样的话复杂度为26*n*m*O(fail). fail可以用kmp进行预处理,将26个字母全部处理出来,这样复杂度就变成了26*n*m. 状态转移看代码(就是一个kmp
