The calves are not so good at speaking. They use funny words for digits.
For calves, the digits from zero to nine are spoken and written as:

0 no 3 ci 6 xa 9 so
1 pa 4 vo 7 ze
2 re 5 mu 8 bi

Larger numbers are created by gluing together the names of the digits. For example, 123 is 'pareci'. A single space can be placed between the digits, so 123 can also be written as 'pa reci', 'pare ci' or even 'pa re ci'.
Help the calves learn arithmetic. Write a program that reads in six numbers of no more than 15 calf digits and sums them. The output, of course, must be in the calf numbers.

A single line with a single calf number that is the sum of the six input calf numbers. The output line contains no spaces.
