Program to accept a sentence which is terminated by ‘.’ or ‘?’ or ‘!’ only. Check for words starting and ending with vowels and arrange then at the start of the whole sentence. Also show the frequency of words starting and ending with vowels.
Note: The words may be separated by more than one space but the program should remove it.
Example: “Susan and Anamika are never going to quarrel again.”. The program is expected to generate new sentence that is “Anamika are Susan and never going to quarrel again.” where frequency of words starting and ending with vowels is 2.
