Lisp Programming - Divide words into syllables

Write a Lisp program that teaches children how to pronounce multisyllable words by dividing them into syllables. Limit your program to deal only with syllables of the following two sequences:

1. vowelconsonantvowel: divide the word after the second vowel.

   Example: analog ---> ana-log

2. vowelconsonantconsonantvowel: divide the word between the two consonants.

   Example: bumper ---> bum-per
