Hey everyone , I'm new at codeforces , but I don't know whether i'm doing something wrong in the code or it's something at codeforces that I don't know.

Here's the code for Codeforces Round #224 (Div. 2) prob 1 : 382A — Ksenia and Pan Scales ,

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main()
{
  int ch,l1,l2,l3;
  ch=getchar();
  string s1,s2,s3;
  while(ch!='|') { s1+=(char)ch; ch=getchar(); }
  ch=getchar();
  while(ch!='\n') { s2+=(char)ch; ch=getchar(); }
  ch=getchar();
  while(ch!=EOF) { s3+=(char)ch; ch=getchar(); }
  l1 = s1.length();
  l2 = s2.length();
  l3 = s3.length();
  int s=0,i,tmp;
  
  if(l1>l2){
    if(l1<=l3+l2) { 
      tmp=l1-l2;
      for(i = 0; i<tmp; i++) { s2+=s3.at(i); l2++; s++; } 
    }
    else { cout << "Impossible" << endl; return 0; }
  }else if(l1<l2){
    tmp=l2-l1;
    if(l2<=l3+l1) for(i = 0; i<tmp; i++) { s1+=s3.at(i); l1++;  s++;}
    else { cout << "Impossible" << endl ; return 0; }
  }
  
  if(l1==l2){
    if((l3-s)%2!=0) { cout << "Impossible" << endl ; return 0; }
    else {
      for(i = s; i<l3 ; i++) { s1+=s3.at(i); i++;  s2+=s3.at(i); }
    }
  }
  cout << s1 << '|' << s2 << endl;
  return 0;
}

I have checked against the test case at ideone and got right answer , but the result here was :

Test: #1, time: 0 ms., memory: 0 KB, exit code: 0, checker exit code: 1, verdict: WRONG_ANSWER
Input
AC|T
L
Output
Impossible
Answer
AC|TL
Checker Log
wrong answer The participant has not answer. But jury has.

I've been wondering as to what the last statement means.Help is always welcome. ThankYou,
