4  4  4  4
5  5  5  5

    void print(int n) - To check whether the number is a lead number. A lead number is the one whose sum of even digits are equal to sum of odd digits.

    e.g. 3669
    odd digits sum = 3 + 9 = 12
    even digits sum = 6 + 6 = 12
    3669 is a lead number.
    Assignment 4

    Define a class to accept a String and print the number of digits, alphabets and special characters in the string.

    Example:
    S = "KAPILDEV@83"
    Output:
    Number of digits – 2
    Number of Alphabets – 8
    Number of Special characters – 1
