Question 2

Vowel Count

Find the number of vowels in a given string irrespective of case.

Input: Onion

Output:2(hint:’O’ & ‘o’ denotes the same vowel, so count is 1 and ‘i’ count is 1. Hence total count is 2)

NOTE: irrespective of case, case insensitive, ignore case all the term holds the same meaning
