Based on the operationcode, you will call three versions of the overlaoded function textProcessing asfollows:●Operation 0: The function removes all vowels from the ORIGINALsentence. The vowels considered are the small letters (a, e, i, o, u y, andw).• Operation 1: The code further asks for one lowercase letter to be inputby the user. If the character is not a lower case letter, the code outputsInvalid.The function returns the distance (difference) between theletter first occurence and last occurence in the text. If the letter doesnot occur in the sentence, it returns 0.• Operation 2: The code asks for two lowercase letters to be input by theuser. If the characters are not lower case letters, the code outputsInvalid.The function replaces the original letter by the new letter in theORIGINAL string.• Any other opcode: the code outputs Invalid.1/0Program Input:• A single line that takes in an operation code.• Zero or one or two lower case letters depending on the operationcodeProgram Output:• Depends on the function called and as specified above
