السلام عليكم
عندي مشكلة في ادخال كاراكترز
هذا كود البرنامج بالكامل

}فــ مثلا انا لو اردت ادخال سطرين من المدخلات مثل
1111 1111 1111 111
2222 22222 2222
//
ووضعت بعد الادخال //
المفروض انه يضيف في اللست two nodes
لكنه بيحسب الــ // على انه نص وبيضيفها داخل اللست
كيف اخليه ما يدخل الـ // لداخل اللست ؟
