1077 Kuchiguse

The Japanese language is notorious for its sentence ending particles. Personal preference of such particles can be considered as a reflection of the speaker’s personality. Such a preference is called “Kuchiguse” and is often exaggerated artistically in Anime and Manga. For example, the artificial sentence ending particle “nyan~” is often used as a stereotype for characters with a cat-like personality:

• Itai nyan~ (It hurts, nyan~)
• Ninjin wa iyada nyan~ (I hate carrots, nyan~)

Now given a few lines spoken by the same character, can you find her Kuchiguse?

Input Specification:

Each input file contains one test case. For each case, the first line is an integer N (2≤N≤100). Following are N file lines of 0~256 (inclusive) characters in length, each representing a character’s spoken line. The spoken lines are case sensitive.

Output Specification:

For each test case, print in one line the kuchiguse of the character, i.e., the longest common suffix of all N lines. If there is no such suffix, write nai.

Sample Input 1:

3
Itai nyan~
Ninjin wa iyadanyan~
uhhh nyan~

Sample Output 1:

nyan~

#include<cstdio>
#include<cstring>

int main()
{
  int N;
  char sentence[100][260]={0};
  int len[100];
  int min = 256;
  char re[256]={0};
  scanf_s("%d\n", &N);
  for (int i = 0; i < N; i++)
  {
    gets_s(sentence[i]);
    len[i] = strlen(sentence[i]);
    if (len[i] < min)
    {
      min = len[i];
    }
    for (int j = 0; j < len[i]/2; j++)
    {
      char temp = sentence[i][j];
      sentence[i][j] = sentence[i][len[i] - 1 - j];
      sentence[i][len[i] - 1 - j] = temp;
    }
  }
  for (int i = 0; i < min; i++)
  {
    int j;
    for (j = 0; j < N-1; j++)
    {
      if (sentence[j][i] != sentence[j + 1][i])
      {
        break;
      }
    }
    if (j == N - 1)
    {
      re[i] = sentence[0][i];
    }
    else
      break;
  }
  if (strlen(re) == 0)
  {
    printf("nai");
  }
  for (int i = strlen(re) - 1; i >= 0; i--)
  {
    printf("%c", re[i]);
  }
  printf("\n");
}

测试点3应该是输入了几个完全相同的长度为256的字符串，如发生错误可检查一下一些常量。如字符数组的大小，最小长度的初始值。
