Write a programExercise 1/4Basic10 XP

The sum from 1 to n

Task

Write a recursive function sucet(n) that returns the sum 1 + 2 + … + n for a non-negative whole n. For n = 0 the sum is 0.

Do not use loops - the function must call itself.

Examples

Call
```
print(sucet(4))
```
Expected output
```
10
```

Rules

Solve it with recursion - no for or while loops.

After you submit, 4 hidden tests will also check your solution: n = 0, n = 1, n = 100, n = 500.

You need to know

Python starts the first time you run code.

def sucet(n):
    pass
# Kód pod touto podmienkou sa spustí, keď program spustíš ty. Testy ho preskočia
# a tvoje funkcie zavolajú priamo.
if __name__ == "__main__":
    print(sucet(4))

Ctrl+Enter runs the program. Tab indents. Press Esc, then Tab, to leave the editor.

Input (stdin)

Each line = one call to input().
