[Help me Plz] Decimal to Binary and "Printing Stars"

[Sylvanuz]

//My Problem on this is i need the output to be reversed
//Example Run:

//Enter a decimal number
//100
//The Decimal Number is: 100
//Its Binary Representation is:
//0010011

//I need the output to be reversed to 1100100
//Without using the .reverse or .IntegerToBinary methods
//Any help would be appreciated
