Ṫ0ẋ24¤;ṙÑs5UY - Link 1, make grid: [row, column, character] e.g. [5,2,'*']
Ṫ - tail: character '*'
¤ - nilad followed by link(s) as a nilad
0 - zero
ẋ - repeated
24 - 24 times [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]
; - concatenate: "000000000000000000000000*"
Ñ - call next link (2) as a monad 21
ṙ - rotate left by "000*000000000000000000000"
s5 - split into chunks of length 5 ["000*0","00000","00000","00000","00000"]
U - upend (reveres each) ["0*000","00000","00000","00000","00000"]
Y - join with line feeds 0*000
- implicit print 00000
00000
’ḅ5 - Link 2, position: [row, column] 00000
’ - decrement 00000
ḅ5 - convert from base 5
Ṗḟ5R¤ - Link 3, input error checking: [row, column, character]
Ṗ - pop: [row, column]
ḟ - filter out values in
5R¤ - range(5): [1,2,3,4,5] - any values not in this remain giving a truthy result
-ÑÇ? - Main link: [row, column, character]
? - ternary if:
Ç - last link (3) as a monad
- - -1 (if truthy - the error identification)
Ñ - next link (1) as a monad (if falsey - the grid)
