pengantar
Untuk mencegah keylogger mencuri kata sandi pengguna, sistem rekening bank tertentu telah menerapkan tindakan keamanan berikut: hanya digit tertentu yang diminta untuk dimasukkan setiap kali.
Misalnya, katakan kata sandi target Anda 89097
, sistem mungkin meminta mereka untuk memasukkan digit ke-2, ke-4 dan ke-5:
997
Atau mungkin mendorong mereka untuk memasukkan angka 1, 3 dan 5:
807
Yang Anda tahu adalah bahwa target Anda memasukkan angka secara berurutan, tetapi Anda tidak tahu di mana posisi mereka dalam kata sandi yang sebenarnya . Yang Anda tahu ada dua angka 9, yang harus ada sebelum jam 7; dan bahwa 8 muncul sebelum 0, dan 0 sebelum 7. Oleh karena itu, ada enam kata sandi yang mungkin:
80997
89097
89907
98097
98907
99807
Keylogger di komputer target Anda telah mengumpulkan input kata sandi selama berbulan-bulan sekarang, jadi mari masuk!
Tantangan
Diberikan daftar input tiga digit, tampilkan semua kata sandi yang mungkin yang valid untuk semua input. Untuk mengurangi kompleksitas komputasi dan untuk menjaga jumlah hasil yang mungkin rendah, kata sandi dijamin numerik dan memiliki ukuran tetap 5. Digit dalam setiap input berurutan: jika 123, target mengetik 1 terlebih dahulu, lalu 2, lalu 3.
