আমি এটি পোস্ট করতে প্রায় লজ্জা পেয়েছি এবং এটি অবশ্যই একটি ভিন্ন পদ্ধতির সাথে খুব বেশি কিছু দ্বারা গল্ফ হতে পারে তবে এটি সম্পূর্ণ হতে কিছুক্ষণ সময় নিয়েছে আমি যেভাবেই পোস্ট করার সিদ্ধান্ত নিয়েছি এবং এখান থেকে এটি গল্ফ করে। চ্যালেঞ্জটি ইমোয়ের চেয়ে সহজ দেখায় তবে আমি অবশ্যই এখানে একটি ভুল পন্থা ব্যবহার করছি এবং আমার মনে হয় যে 05 এবি 1 ই প্রায় 25 বাইট করতে পারে ..
এটি অনলাইনে চেষ্টা করুন। দ্রষ্টব্য: এটি কেবল দীর্ঘ নয়, এটি অদক্ষও, যেহেতু 9x4
