Challenge #6 - Code #3 - Explanation

The Input of http://pastebin.com/F9ZDQZYC is: "THE EYES ARE USELESS WHEN THE MIND IS BLIND".


Code #3 is like Code #1 but you're now able to use multiple instances of the same letter and its output varies.

Our input will be: "HELLO WORLD" and we'll encode one word at a time.

HELLO is 5 characters long, meaning we need to make a 5x5 square & fill in the alphabet.

	1	2	3	4	5
1	A	B	C	D	E
2	F	G	H	I	J
3	K	L	M	N	O
4	P	Q	R	S	T
5	U	V	W	X	Y

Since we've filled the whole 5x5 square with most of the alphabet(A-Y), the "Z" will be apart of the next group(A) of 5x5 squares.

------------1st GROUP has no Group letter------------
	1	2	3	4	5
1	A	B	C	D	E
2	F	G	H	I	J
3	K	L	M	N	O
4	P	Q	R	S	T
5	U	V	W	X	Y
------------2nd Group will be defined by "A"------------
	1	2	3	4	5
1	Z	_	_	_	_
2	_	_	_	_	_
3	_	_	_	_	_
4	_	_	_	_	_
5	_	_	_	_	_


Our output will now have a padding of "X"'s, and it will be as long as how many spots are in the group (in this case, 5x5=25)

XXXXXXXXXXXXXXXXXXXXXXXXX


Just like Code #1, Knowing the number form of letters, A=1,B=2,C=3...Z=26, We now place the order letter in the position of the letter's number.

(H)ELLO		XXXXXXX1XXXXXXXXXXXXXXXXX

If our first letter happened to be "Z", then we would know that "Z" is apart of GROUP A, BUT is in the 1st postion in the 5x5 grid, meaning:

Our Z, (1st character being encoded: Order number = 1), would be in the 1st postion of our output:

(Z)ello		(X)XXXXXXXXXXXXXXXXXXXXXXXX

(Z)ello		(1)XXXXXXXXXXXXXXXXXXXXXXXX

Since "Z" is in Group A, we need to show that in your output by adding ".A" after the "1":

(Z)ello		(1.A)XXXXXXXXXXXXXXXXXXXXXXXX

and it would look like this:

(Z)ello		1.AXXXXXXXXXXXXXXXXXXXXXXXX


Now back to our actual input: H(E)LLO

H(E)LLO		XXXX2XX1XXXXXXXXXXXXXXXXX

HE(L)LO		XXXX2XX1XXX3XXXXXXXXXXXXX


Now we have a 2nd instance of the same letter (two L's), All we do to show that multple letters are apart of that position is add a "|" between them:

HEL(L)O		XXXX2XX1XXX3|4XXXXXXXXXXXXX

HELL(O)		XXXX2XX1XXX3|4XX5XXXXXXXXXX


and if we had to encode a letter from a different group, same rules apply.

If you find it a bit hard to understand when trying to decode, space out the columns:

Final:
HELLO = XXXX2XX1XXX3|4XX5XXXXXXXXXX

Final with 25 columns spaced out:
HELLO = X	X	X	X	2	X	X	1	X	X	X	3|4	X	X	5	X	X	X	X	X	X	X	X	X	X


To save time, Here is how the rest of the input would look:


HELLO WORLD:

XXXX2XX1XXX3|4XX5XXXXXXXXXX
XXX5XXXXXXX4XX2XX3XXXX1XXX


Essentially, you can also do the same thing as Code #1 and repeat the numbers if you wanted to:

HELLO WORLD:

222221113333|45552222222222
55554444444422233311111555


That's all there is to this code. :D

Thanks for participating for Code #1! :D
