Dasturchilarning eng sevimli so'zlaridan biri bu "kod" so'zi. Sizga chiziq berilgan. Sizning vazifangiz - "kod" so'zini o'z ichiga olgan satrda so'zlarni topish.

Kirish bitta qatorni o'z ichiga oladi. U inglizcha kichik va katta harflar va bo'shliqlardan iborat bo'lishi mumkin. Bo'shliq bilan ajratilgan so'zlar. Chiziqning boshida va oxirida bo'sh joy yo'q. Chiziqning uzunligi 1000 dan oshmaydi.
