Task Given an input string of 7-bit ASCII characters, do the following: Convert each character into its 7-bit ASCII code Concatenate all bits (this results in 7*n bits where n is the number of characters) For each bit in this bitstream, print 1 if it is the same as the previous bit, and print ...

Given a start word and a target word, print the "mutation chain" that starts at the start word and ends at the target word. You may assume both words are lowercase and only have alphabetic characters. Define a "mutation" as the removal of an character, the insertion of a character, or the alter...

This is a probably structure I found studying the Collatz Conjecture Pictured is structure the from y coordinate 0 to 27 Note that at even y-coordinates the structure expands in the x-direction, and at 0 and 5 mod 6 in the z-direction. Expect for the very top block. If you collapse the z-co...

Task Scramble the English alphabet so that it can still be sung to the tune Twinkle Twinkle Little Star as it traditionally is. Let's just assume the following groups of letters can be switched freely by default without ruining the tune: { A, J, K } { B, C, D, E, G, P, T, V, Z } { I, Y } { Q...

What general tips do you have for golfing in Grass? I'm looking for ideas which can be applied to code-golf problems and which are also at least somewhat specific to Grass (e.g. "remove no-op characters" is not an answer). Please post one tip per answer.

please can anyone explain with out the use of any programming language tool, what is the rule for converting a code segment,(not an expression) to postfix notation....Thank you I appreciate in advance of your responses

This is perhaps one of the classical coding challenges that got some resonance in 1986, when columnist Jon Bentley asked Donald Knuth to write a program that would find k most frequent words in a file. Knuth implemented a fast solution using hash tries in an 8-pages-long program to illustrate his...

Jimmy has had a busy last week with all these platforms and ropes, and poor Jimmy doesn't even have legs or feet to stand on! Your job is to take a string containing multiple Jimmys and give them legs and shoes! Get input in the form of a Jimmy String Jimmy String => /o\ /o\ /o\ containi...

This is a Cops and Robbers challenge. This is the cop's thread. The robber's thread is here. As a cop, you must pick any sequence from the OEIS, and write a program p that prints the first integer from that sequence. You must also find some string s. If you insert s somewhere into p, this progra...

The task here is to write a program that takes an natural number, \$n\$, and produces the \$n\$th term of an OEIS sequence. That sequence should have an identifier in the form of A followed by 6 digits. Now when you take your source code and reverse the order of it's bytes to produce a new prog...

(we won't be finding a Find or catching a tryCatch, though) This is part two of a multi-part series of implementing some interesting R functions. Part one can be found here. The task: You are to implement R's match function in as few bytes as possible. Input: x, a possibly empty list/array ...

Calculate Complimentary Color Write a function that outputs or returns the 3 bytes of an RGB color that is complimentary to the input color. The input may be taken directly as 3 separate inputs, an array of 3 values, or a single 3 byte (Or greater, however the 3 lower bytes should be used) inpu...

In the tabletop RPG named Pathfinder, there is a feat that characters can take called Sacred Geometry, which allows a character who has it to buff their spells in exchange for doing some math: to use it, the character rolls a number of six-sided dice equal to their ranks in a particular skill, co...

150 rep for an R answer to this question You cannot use match or %in%. The former for obvious reasons, the latter because %in% is implemented as function(x,table)match(x,table,0) > 0. Sufficiently golfy answers will, at my discretion, be awarded more rep. First one to be posted will get the pri...

Help! I seem to have an annoying echo in some of my floating point arrays, and I'd like to get rid of it. When this occurs, the original array repeats itself somewhere in the middle causing the values to be added to each other. For example, the array [ 42.2, 37.5, 52.7, 37.5, 85.9, 45.1, 75.4,...
