Replace all vowels with next consonant in a given string

Objective: Given a string, write an algorithm to replace all the vowels with next consonant, and if last alphabet is vowel, remove it.

Example:

String input: “abcdefg”
Output: “bbcdffg”

String input: “aaaabccceee”
Output: “bbbbbccc”

String input: “aaa”
Output: “”

Approach:

• Traverse the string right to left one character at a time.
• Maintain a variable , last_visited_non_vowel
• During traversal , when vowel is encountered, replace it with , last_visited_non_vowel and add to result.
• During traversal , when consonant(non vowel) is encountered, update the last_visited_non_vowel and add to result.
