UTF-1 is a method of transforming ISO 10646/Unicode into a stream of bytes. Its design does not provide self-synchronization, which makes searching for substrings and error recovery difficult. It reuses the ASCII printing characters for multi-byte encodings, making it unsuited for some uses (for instance Unix filenames cannot contain the byte value used for forward slash). UTF-1 is also slow to encode or decode due to its use of division and multiplication by a number which is not a power of 2. Due to these issues, it did not gain acceptance and was quickly replaced by UTF-8.

Print this matrix without embedding its values directly in the program:
1 8 9 16
2 7 10 15
3 6 11 14
4 5 12 13
Exact format does not matter as long as there is 4 lines and a separator between values.
Given a number n (n>1) generate a table like below.
For number 5,
1 2 3 4 5
2 2 3 4 5
3 3 3 4 5
4 4 4 4 5
5 5 5 5 5
For number 8,
1 2 3 4 5 6 7 8
2 2 3 4 5 6 7 8
3 3 3 4 5 6 7 8
4 4 4 4 5 6 7 8
5 5 5 5 5 6 7 8
6 6 6 6 6 6 7 8
7 7 7 7 7 7 7 8
8 8 8 8 8 8 8 8

I started one code golf challenge recently and it seems like the winner is GolfScript (surprise, surprise!). What's interesting is that there was another very strong competitor that had all chances to win over GolfScript. Its name is APL. I see a lot of answers written in APL here. It seems like ...
