Problems come with statements in English and in Bangla. Switch whenever you like.
First Words
In 1972 Brian Kernighan wrote a short tutorial at Bell Labs for a language called B. One of its examples printed just two words: hello, world. Six years later the same greeting opened The C Programming Language, the book Kernighan wrote with Dennis Ritchie, and it never left. Since then almost every programmer's first program has said hello to someone.
Keep the tradition going. Your program has one job: greet the world.
প্রথম কথা
1972 সালে Bell Labs-এ Brian Kernighan, B নামের একটা language-এর জন্য ছোট্ট একটা tutorial লিখেছিলেন। সেখানে একটা উদাহরণ ছিল, যেটা শুধু দুটো শব্দ print করত: hello, world। ছয় বছর পর Kernighan আর Dennis Ritchie মিলে লিখলেন The C Programming Language, আর বইটা শুরুই হলো ওই একই অভিবাদন দিয়ে। তারপর থেকে প্রায় সব programmer-এর প্রথম program কাউকে না কাউকে hello বলে।
ঐতিহ্যটা ধরে রাখো। তোমার program-এর কাজ একটাই: পৃথিবীকে hello বলা।
Samples run first, then the hidden tests. You see each sample's result, how many hidden tests passed, and the compiler's output when a build fails.

ICPC-style standings, with a freeze
Standings freeze near the end and unfreeze after the clock. Solo rounds, or teams of three.

A rating that moves with every rated round
Everyone starts at 1200 and shows as unrated until their first rated round. Each rated round after that moves it, on your profile and on the leaderboard.
