Haikus are poems formed by three lines of 5, 7, and 5 syllables. Your task is to write a function that determines if a given poem scans as a Haiku.
How to count syllables:
- Every syllable must contain at least one vowel.
- If two or more vowels appear back to back, they should be counted as a single vowel (e.g. "fair").
- If an "e" appears at the end of a word, it shouldn't be counted, as those aren't usually pronounced. That extends to words ending in
es or e's.
- An exception to the previous point is a word whose only vowel appears at the end (e.g. "the" or "She's").
- "Y" counts as a vowel.
Examples
haiku("New vids ev'ry day / Never skipped a single day / I'll see you in March") ➞ true
haiku("Delightful display / Snowdrops bow their pure white heads / To the sun's glory") ➞ true
haiku("Superman's my fav / Wonder Woman is pretty dope / Don't forget Rorschach") ➞ false
Notes
- Each new line of the poem will be marked with a
/.
- You may find commas, apostrophes, and other punctuation marks.
