Your task is to write a program that outputs its own source code in reverse. However, when the reversed code is run, it should output the source code, facing the correct direction. Example Say your program is abc. When run, it should output cba. cba, when run, should output abc. Rules Your pr...

Tetris Programming code-challengerestricted-sourcetetris The Task Your program or function should take as input one character from the set IJLOSTZ, which represents one of the seven tetrominos as usual: I J L O S T Z # # # ## ## ### ## # # # ## ## # ## # #...

Given a dictionary of 4-letter words that have no repeated characters (from this list of words), you must choose ONE of those words, and output that specific word using the following dictionary of block letters: .----------------. .----------------. .----------------. .----------------. | ....

Make a program (or a function) that copies the exact text "Hello, World!" to the clipboard, and terminates.

Slow growing Quine Make a Quine. Seems easy right? Well this quine must output a quine + one extra character which then outputs itself + another character. This way the quine should in several generations output two copies. Example: Lets supose your code is foobar foobar foobarf foobarfo foo...

given a string with white spaces, I need to double each white space but the restrictions are: can't allocate more than O(1) space (only fixed number of variables) changes must be made on the original string can't write to the same cell of the string more than once For example input: < space >Hi<...

Given a list of (key, value) pairs, determine whether it represents a function, meaning that each key maps to a consistent value. In other words, whenever two entries have equal keys, they must also have equal values. Repeated entries are OK. For example: # Not a function: 3 maps to both 1 an...

Explanation of the challenge Given an input, return what shapes it could be. There are only a couple options. Square Triangle Square A square is in the following format: XXXX XXXX XXXX XXXX So, in this example, the input would be: 16 And the output would be: 1 or "Square" Triang...

Given a positive integer n write some code to take its prime factorization and replace all of its factors of 2 with 3. For example 12 = 2 * 2 * 3 -> 3 * 3 * 3 = 27 This is code-golf so the goal is to minimize the byte count of your answer. Test cases 1 -> 1 2 -> 3 3 -> 3 4 -> 9 5 -> 5 6 -> ...

A collection of N dimensional coordinates are provided. An example is below: {2,3,4} This can be thought of as a 3 dimensional array with 2x's, 3y's and 4z's; there may be any number of dimensions. In the example, there are 24 total nodes. Each node can be indexed using {x,y,z}. To access the ...
