Input stdin
Output
Press Run to see the output.
Your code runs in an isolated sandbox with its own CPU and memory limits — never on this site’s own server — and nothing you write is stored or shown to anybody else.
Reads input properly
Type into the input box and your program receives it on stdin —
input(), scanf, cin and Scanner
all work as they would on your own machine.
Keeps your work
Whatever you write is saved in your own browser, per language, so closing the tab by accident does not lose it.
Then go practise
When you want a target instead of a blank page, the practice problems check your answer automatically.
