You are developing a game that allows players to collect from 0 through 1000 coins. You are creating
a method that will be used in the game. The method includes the following code. (Line numbers are
included for reference only.)

The “#” Custom Specifier
The “#” custom format specifier serves as a digit-placeholder symbol. If the value that is being formatted has a digit in the position where the “#” symbol appears in the format string, that digit is copied to the result string. Otherwise, nothing is stored in that position in the result string.
Note that this specifier never displays a zero that is not a significant digit, even if zero is the only digit in the string. It will display zero only if it is a significant digit in the number that is being displayed
e.g
value = 123;
Console.WriteLine(value.ToString(“#####”));
Console.WriteLine(String.Format(“{0:#####}”, value));
// Displays 123
