Are they all different?

Task

The input is a line of whole numbers separated by spaces. The program prints áno (yes) if all the numbers are different, otherwise nie (no).

Comparing the length of the list with the length of a set of the same numbers helps.

Examples

  • Input

    1 2 3

    Expected output

    áno

  • Input

    1 2 1

    Expected output

    nie
