Problem
Snuke, a cat, wants to play the popular Japanese game "ÅtCoder". Therefore, Iroha-chan decided to teach Snuke Japanese.
In Japanese, when counting pencils, you attach the counter word "hon" after the number. The reading of this counter word "hon" differs depending on the number. Specifically, when using the expression "N hon" to mean "N pencils", it is read as follows:
When the last digit of N is 2, 4, 5, 7, or 9, it is read as "hon".
When the last digit of N is 0, 1, 6, or 8, it is read as "pon".
When the last digit of N is 3, it is read as "bon".
Given N, write a program to output how to read "N hon" using the counter word "hon".
Constraints
N is an integer between 1 and 999 (inclusive).
