I. Deer is Better!

Time limit: 1.0 second
Memory limit: 64 MB
A crow is sitting on a branch with a piece of cheese in its mouth.
A fox is running by:
“Crow, are you going to the election?”
The cheese falls down. The crow sits thinking:
“Would anything have changed had I said yes?”
A Chukcha set out to go to the election. There are l kilometers between his yaranga and the polling station. His deer run so that they cover every k-kilometer segment of the way in exactly h hours. What is the minimal and maximal time in which the Chukcha will be able to perform his civic duty?


The only input line contains space-separated integers l, k, and h (1 ≤ k ≤ l ≤ 1000; 1 ≤ h ≤ 1000).


Output the minimal and maximal time in which Chukcha can get from his yaranga to the polling station, accurate to at least 10–5. The numbers must be separated with a space.
