back to boardhelp with aho corasick MLE 7! I can't think of a way to store goto and fail transitions of so many vertices and avoid MLE. please help. here's code: #include <stdio.h> #include <queue> using namespace std; short g[110000][256]; short f[110000]; short o[110000]; short n,m,newstate=0; queue<short>Q; int main(void){ short i,pos=0,q,r,u,v,ch,state; scanf("%hd",&n);getchar(); for(i=1;i<=n;++i){ r=0; ch=getchar(); state=0; ++r; ch+=128; while(g[state][ch]){ state=g[state][ch]; ch=getchar(); ++r; ch+=128; } while(ch!='\n'+128){ newstate=newstate+1; g[state][ch]=newstate; state=newstate; ch=getchar(); ++r; ch+=128; } o[state]=r-1; } for(i=0;i<256;++i){ if(q=g[0][i]){ f[q]=0; Q.push(q); } } while(!Q.empty()){ r=Q.front(); Q.pop(); for(i=0;i<256;++i){ u=g[r][i]; if(!(u==0&&r>0)){ Q.push(u); v=f[r]; while(g[v][i]==0&&v>0) v=f[v]; f[u]=g[v][i]; if(o[u]==0) o[u]=o[f[u]]; } } } scanf("%hd",&m);getchar(); for(i=1;i<=m;++i){ q=0;r=0; while((ch=getchar())!='\n'){ ch+=128; ++r; while(g[q][ch]==0&&q>0) q=f[q]; q=g[q][ch]; if(o[q]){ printf("%hd %hd",i,r-o[q]+1); return 0; } } } printf("Passed\n"); return 0; } Re: help with aho corasick MLE 7! you got pretty close, modified your solution to get AC. let me know if you need hints :) ikhomeriki@gmail.com Edited by author 21.09.2018 23:04 |
