The program must accept a string S as the input. The program must replace all the vowels in S by
the vowels a, e, i, o and u in a circular manner. Finally, the program must print the modified string
as the output.
Note: All the alphabets in S are only in lower case.
Boundary Condition(s):
1 <= Length of S <= 100
Input Format:
The first line contains the string value S.
Output Format:
The first line contains the modified string value of S.
Example Input/Output 1:
Input:
kingkong
Output:
kangkeng
Explanation:
The vowels in the string kingkong are i and o. So they are replaced by a and e.
Hence the output is kangkeng
Example Input/Output 2:
Input:
icecreamchocolate
Output:
acecriomchucaleti
