@JohnRennie hi

John Rennie

@Tanuj hi :-)

Tanuj

i was solving a problem on codeforces

and i dont know why I'm getting the error that I'm getting

codeforces.com/problemset/problem/263/A

this is the question

and this is my attempt to solve it

paste.ofcode.org/xqWxbNcMLja8wCHYFanHzh

and the error I get is : Runtime error: exit code is -1073741819

@JohnRennie oof nevermind

I figured it out

arrays are indexed from 0 and not 1

so my matrix mat[i][j]

should be mat[6][6] and not mat[5][5]

John Rennie

OK :-)

@Tanuj It's a typo. The line:

   for(int j=i+2;i<s.size();j+=2)

should be:

   for(int j=i+2;j<s.size();j+=2)

Although your code still isn't working in all cases e.g.

int main()
{
  string s = "6+5+4+3+2+1";
  char temp;
  for(int i=0; i<((s.size()+1)/2); i+=2)
  {
    for(int j=i+2; j<s.size(); j+=2)
    {
      if(s[i]>s[j])
      {
        temp=s[j];
        s[j]=s[i];
        s[i]=temp;
      }
    }
  }
  cout<<s;

  return 0;
}

prints:
