# Program for Decimal to Binary Conversion

    Given a decimal number as input, we need to write a program to convert the given decimal number into equivalent binary number.

    Examples:

        Input : 7
        Output : 111

        Input : 10
        Output : 1010

        Input: 33
        Output: 100001
