Problem ID: 11713

Note that for the following input

1
book
bake

The expected output is "No" because the second "o" cannot be replaced by another vowel at that position (because "b" is a consonant).

The following transformation is not legal

book --> bak (by replacing the "oo" by "a") --> bake (by adding the letter "e")

The judge's input likely does not contain such test cases anyway.
