Polybius square cipher - encode

Implement the Polybius square cipher.

Replace every letter with a two-digit number. The first digit is the row number, and the second digit is the column number of following square. Letters 'I' and 'J' are both 24 in this cipher:

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

Input will be valid (only spaces and uppercase letters from A to Z), so no need to validate them.

Examples

Solution.polybius("A")  // "11"
Solution.polybius("IJ") // "2424"
Solution.polybius("CODEWARS") // "1334141552114243"
Solution.polybius("POLYBIUS SQUARE CIPHER") // "3534315412244543 434145114215 132435231542"
