1. Write a value-returning method, isVowel, that returns the value true if a given character
is a vowel, and otherwise returns false. Also write a program to test your method.
2. Write a program that prompts the user to input a sequence of characters and outputs the
number of vowels. (Use the method isVowel written in Programming question 1.)
3. Write a program that uses the method sqrt of the class Math and outputs the square roots
of the first 25 positive integers. (Your program must output each number and its square
root.)

with its digits reversed. For example, the value of reverseDigit(12345) is 54321. Also,
write a program to test your method.
