Açıklama:
Z # Get the maximum of the (implicit) input-matrix (implicitly flattened)
# (and without popping the matrix)
# i.e. [[8,0,6],[0,5,0],[0,0,2]] → 8
s # Swap to get the input-matrix again
g # Get its length (amount of rows)
# i.e. [[8,0,6],[0,5,0],[0,0,2]] → 3
n # Square it
# i.e. 3 → 9
© # Store it in the register (without popping)
>‹ # Check if the maximum is <= this squared matrix-dimension
# i.e. 8 <= 9 → 1 (truthy)
® # Push the squared matrix-dimension again
L # Create a list in the range [1, squared_matrix_dimension]
# i.e. 9 → [1,2,3,4,5,6,7,8,9]
¹ # Push the input-matrix
˜ # Flatten it
# i.e. [[8,0,6],[0,5,0],[0,0,2]] → [8,0,6,0,5,0,0,0,2]
K # Remove all these numbers from the ranged list
# i.e. [1,2,3,4,5,6,7,8,9] and [8,0,6,0,5,0,0,0,2] → [1,3,4,7,9]
œ # Get all possible permutations of the remaining numbers
# (this part is the main bottleneck of the program;
# the more 0s and too high numbers, the more permutations)
