## Dailyprogammer Challenge #199 - Bank Numbers Pt 1

I have attempted another dailyprogammer challenge on reddit.

This time, the challenge is to take a number in and print a 'banner' representing that number, like this:

Input: 47262

Output:
_  _  _  _
|_|  | _||_  _|
|  ||_ |_||_

Here is my solution:

using System;

public class BigDigits
{
static string[,] bannerTemplates = new string[,]{
{ " _ ", "| |", "|_|" },
{ "   ", "  |", "  |" },
{ " _ ", " _|", "|_ " },
{ " _ ", " _|", " _|" },
{ "   ", "|_|", "  |" },
{ " _ ", "|_ ", " _|" },
{ " _ ", "|_ ", "|_|" },
{ " _ ", "  |", "  |" },
{ " _ ", "|_|", "|_|" },
{ " _ ", "|_|", " _|" }
};

static void Main(string[] args)
{
if (args.Length == 0)
{
Console.WriteLine("This program converts a number to a banner.");
Console.WriteLine("\nUse it like this: ");
Console.WriteLine("    bigintbanners.exe <number>");
Console.WriteLine("\n<number>: The number you want to convert.");
return;
}

char[] intChars = args[0].ToCharArray();
string[] resultLines = new string[3];
int currentDigit = 0;

int i = 0;

for(i = 0; i < intChars.Length; i++)
{
currentDigit = int.Parse(intChars[i].ToString());
for (int j = 0; j < 3; j++)
{
resultLines[j] += bannerTemplates[currentDigit,j];
}
}

for(i = 0; i < resultLines.Length; i++)
{
Console.WriteLine(resultLines[i]);
}
}
}

I find the dailyprogrammer challenges to be a great way to practice a language that you are learning.
