啦啦啦二十分钟默出来编译通过,一会去试几道题好啦

#include <iostream>
#include <cstdio>
#include <cstring>
using namespace std;
const int maxn = 10005;
const int maxm = 100;
int n, tot, temp;
int ch[maxn][maxm], fail[maxn], flag[maxn], que[maxn];
int cal(char c)
{
    return c-'a';
}
void newnode(int x,int temp)
{
    ch[x][temp] = ++tot;
    //还有别的我懒得写2333333
}
void addtrie(char s[])
{
    int x = 0, p = 0;
    int len = strlen(s);
    while( p < len )
    {
        temp=cal(s[p]);
        if( !ch[x][temp] ) newnode(x, temp);
        x = ch[x][temp];
        p++;
    }
    flag[x] = true;
}
void getfail(void)
{
    int h = 0, t = 0;
    for(int i = 0; i < maxm; i++)
        if( ch[0][i] ) que[t++] = ch[0][i];
    while( h < t )
    {
        temp=q[h++];
        //flag[temp]|=flag[fail[temp]];
        for(int i = 0; i < maxm; i++)
            if( !ch[temp][i] ) ch[temp][i] = ch[fail[temp]][i];
            else
            {
                que[t++] = ch[temp][i];
                fail[ch[temp][i]] = ch[fail[temp]][i];
            }
    }
