Given a string “str”, the task is to duplicate vowels in this string.
Input: str = "geeks" Output: geeeeks Input: str = "java" Output: jaavaa
Approach: Iterate the string using a loop. Check if the character is a vowel and duplicate it. Return
then print the resultant string.
Below is the implementation of the above approach:
Original String: helloworld String with Vowels duplicated: heelloowoorld
- Program to remove vowels from a String
- C program to count number of vowels and consonants in a String
- Program to count vowels in a string (Iterative and Recursive)
- Python program to count number of vowels using sets in given string
- Program to count vowels, consonant, digits and special characters in string.
- Check if a string can be converted to another string by replacing vowels and consonants
- First X vowels from a string
- Modify the string such that it contains all vowels at least once
- Reverse vowels in a given string
- Count the pairs of vowels in the given string
- Remove consecutive vowels from string
- Permutations of string such that no two vowels are adjacent
- Program to accept a Strings which contains all the Vowels
- Replace all consonants with nearest vowels in a string
- Print reverse string after removing vowels
