Count the Syllables

Create a function that returns the number of syllables in a simple string. The string is made up of short repeated words like "Lalalalalalala" (which would have 7 syllables).

Examples

count_syllables("Hehehehehehe") ➞ 6

count_syllables("bobobobobobobobo") ➞ 8

count_syllables("NANANA") ➞ 3

Notes

• For simplicity, please note that each syllable will consist of two letters only.
• Your code should accept strings of any case (upper, lower and mixed case).
