Day 2: Loops Solution

Objective

In this challenge, we practice looping over the characters of string.

Task

1. First, print each vowel in s on a new line. The English vowels are a, e, i, o, and u, and each vowel must be printed in the same order as it appeared in s.
2. Second, print each consonant (i.e., non-vowel) in s on a new line in the same order as it appeared in s.

Function Description

Complete the vowelsAndConsonants function in the editor below.
vowelsAndConsonants has the following parameters:

• string s: the string to process

Prints

• Print each vowel of s in order on a new line, then print each consonant in order on a new line. Return nothing.

Input Format

There is one line of input with the string s.

Output Format

First, print each vowel in s on a new line (in the same order as they appeared in s). Second, print each consonant (i.e., non-vowel) in s on a new line (in the same order as they appeared in s).

Explanation 0

Observe the following:

• Each letter is printed on a new line.
• Then the vowels are printed in the same order as they appeared in s.
• Then the consonants are printed in the same order as they appeared in s.
