Terinspirasi oleh Alex yang mulia. Pelajari Anda R untuk kebaikan besar, kita akan dengan rendah hati menciptakan kembali "satu program R yang benar" Alex - tetapi dengan twist.
Alex-style Addition bekerja seperti ini - ia memiliki peluang 90% untuk hanya mengembalikan jumlah dari dua angka yang diberikan dan peluang 10% untuk Alex secara rekursif menambahkan angka pertama dan angka kedua + 1. Ini berarti bahwa, berpotensi , tambahan bisa dimatikan oleh 1 atau lebih.
Tantangan
Tulis program atau fungsi lengkap yang membutuhkan dua bilangan bulat dan Alex-menambahkannya sesuai definisi. Anda dapat berasumsi bahwa program Anda tidak akan menumpuk overflow jika bahasa Anda tidak memiliki rekursi ekor. (Perhatikan bahwa Anda tidak harus mengimplementasikannya secara rekursif, asalkan probabilitasnya sama.)

if(i == 1) {
