Consider binary block diagonal matrices which have square blocks of 1s on the main diagonal, and are 0 everywhere else. Let's call such matrices "valid" matrices.
For example, here are some valid 4x4 matrices:
1 0 0 0 1 1 0 0 1 0 0 0 1 0 0 0 1 1 0 0 1 1 1 1
0 1 0 0 1 1 0 ...
Your task is simple: print all the identifiers your language considers keywords, separated by either spaces, tabs, or newlines (whichever is most convenient, though only one whitespace token is permitted between keywords). The keywords may appear in any order.
A language is considered to have k...

I'd like to reverse the order of lines in a text file (or stdin), preserving the contents of each line.
So, i.e., starting with:
foo
bar
baz
I'd like to end up with
baz
bar
foo
Is there a standard UNIX commandline utility for this?
Maintain a list of exemplary challenges
We would have a post on meta. In this post, each answer would consist of a summary of an exemplary challenge and a link. Each such answer would serve as a nomination, and challenges whose nominations that receive a certain number of upvotes would be consid...
We don't have enough (semi-)easy challenges for beginners. More and more of the easy ones are already taken. So I tried to come up with something that might be achievable by beginners, but that isn't a duplicate.
Input:
A single string separated with your OS new-line (i.e. \r\n),
or an array wi...
Every so often old challenges are found which no longer meet our requirements, resulting in them being closed. Since there is renewed interest in this question it is in danger of suffering the same fate.
I find the question interesting, and a number of people are actively working on a collaborat...
The Hofstadter-Conway $10, 000 sequence is defined as follows
The first few terms of this sequence are:
1, 1, 2, 2, 3, 4, 4, 4, 5, 6, 7, 7, (sequence A004001 in OESIS)
This sequence has many interesting properties and one of them can be phrased as follows:
On July 15 1998, John Conwa...
In my recent question about the Fransén-Robinson constant, an answer was given using the Gamma reflection formula. However, as an AP Calculus student, I didn't quite understand how the reflection formula worked. After two days of research, I have only found explanations for the Gamma reflection f...
