This is my code:

#include <iostream>
#include <cmath>

using namespace std;
int main()
{
    int a[101], n, x, dis1 = 0, dis2 = 0, lb, rb;
    bool flag = false, flag2 = false;

    cin >> n >> x;

    if ((x == 0))
      flag2 = true;
    else
    {
      if ( n == 0 )
        flag = true;
    }

    for ( int i = 0; i < n; i++ )
    {
      cin >> a[i];
      if ( (x > 0) && (a[i] < x) && (a[i] > 0) )
        flag = true;

      if ( (x < 0) && (a[i] > x)  && (a[i] < 0) )
        flag = true;
    }

    if (flag)
      cout << "Impossible" << endl;
    else
    {
      lb = a[0];
      rb = a[0];
      for ( int i = 1; i < n; i++ )
      {
        if ( (a[i] > 0) && (a[i] > rb) && (a[i] > x) )
          rb = a[i];

        if ( (a[i] < 0) && (abs(a[i]) < abs(lb)) && (a[i] < x) )
          lb = a[i];
      }

      if ( x > 0 )
      {
        dis1 = x;
        dis2 = (int) abs(2*lb) + x;
      }
      else
      {
        dis1 = 2*rb + (int) abs(x);
        dis2 = (int) abs(x);
      }

      if (flag2)
        cout << "0 0" << endl;
      else
        cout << dis1 << " " << dis2 << endl;
    }

    system("PAUSE");
    return 0;
}

I can't understand WHY WA#4
Please, help!!!

It's too hard code. The real solution is much easier/
