10115 - Automatic Editing

[robertoflores]

all,

be aware that -- contrary to what is stated in the problem description -- the program's filename & I/O are as usual: Main class, input with System.in & output with System.out.

AC-ed with Java!

I don't know that's why always wrong,I check it over and over again,but I still didn't check out where the wrong.
Help me with solve it.
This is my source code:

Code: Select all

#include <stdio.h>
#include <string.h>
#define MAXN 1000
char str[MAXN]={'\0'},rules[11][82]={'\0'},replace[11][82]={'\0'};
char s1[MAXN]={'\0'},s2[MAXN]={'\0'};
int n;
void Autoedit(char *str,char *rule,char *rep)
{
     int len=strlen(str),lr=strlen(rule),k=0;
     for(int i=0;i<=len-lr;i++)
     {
        memset(s1,0,sizeof(s1));
        sprintf(s1,"%.*s",lr,str+i);
        if(!strcmp(s1,rule))
        {
           memset(s1,0,sizeof(s1));
           memset(s2,0,sizeof(s2));
           sprintf(s1,"%.*s",i,str);
           for(int j=i+lr;j<len;j++) s2[k++]=str[j];
           memset(str,0,sizeof(str));
           sprintf(str,"%.*s%s%s",strlen(s1),s1,rep,s2);
           len=strlen(str);
           k=0; i--;
        }
     }
}
int main()
{
    freopen("autoedit.in","r",stdin);
    freopen("autoedit.out","w",stdout);
    while(true)
    {
       scanf("%d\n",&n);
       if(n==0) break;
       for(int i=0;i<n;i++)
       {
          gets(rules[i]);
          gets(replace[i]);
       }
       gets(str);
       for(int i=0;i<n;i++)
          Autoedit(str,rules[i],replace[i]);
       printf("%s\n",str);
    }
    return 0;
}


Hope everyone will help me to solve it.

i am getting wrong answer...

may be there is a small mistake in my understanding...

the rules are to be checked everytime from the begining that is rule 1 right?

so how do you explain this?

No shababhsiddique, the 2 rule states that when you are done with one rule you are to move to the next rule and you cant use the rules used already. I had some troubles with this problem... but I'm quite sure that the WA that you guys are getting are because of the 3 rule in the problem statement.

I'm so steamed up over this problem ....A very easy problem and I got Accepted in first try. However, my code(I coded it in C) although getting a direct Accepted in cpp, always gets Runtime Error in C. Can anyone explain why this is so? What can be the reason?
An advanced thanks for helping Yet another one for reading this
