Many programming language provide operators for manipulating the binary (base-2) digits of integers. Here is one way to generalize these operators to other bases: Let x and y be single-digit numbers in base B. Define the unary operator ~ and binary operators &, |, and ^ such that: ~x = (B - ...

Similar to What's a string? If a challenge says that the input will be “a number”, what data types are acceptable? Obviously, types like int and float are numeric. What about strings? Command-line arguments and stuff read from standard input will naturally be string or sequence-of-char object...

You are trapped in this 5x5 labyrinth - each room is labelled from 1 to 25 and the exit is in room 1. You are given as input the room you are currently in. Your task is to output the shortest sequence of moves (north, east, south, west) needed to reach room 1. Moves can be given in any format...

Include Void main(){ Int x = 5; Printf("%d,%d,%d",x,x++,x); }

This question just trended over on code-review and I figured you might like it adapted as a codegolf challenge: You are given a non-empty list of x houses represented as booleans. Each day, the houses compete with adjacent ones. 1 represents an "active" house and 0 represents an "inactive" house...

The Celestial Bureaucracy In Imperial China, ranks in society were not decided by birth or wealth, but by a person's ability to excel in the Imperial Examinations. The Jade Emperor, divine ruler of the Heavens, has called for all his subjects to be examined to determine their worth, and whom to ...

Your task, if you wish to accept it, is to write a program that outputs a non-zero number(can be integer or float). The tricky part is that if I reverse your source code, the output must be the original integer negated. Rules You must build a full program. That is, your output has to be printe...

Duct Tape a Regex Decider duct-tape-coding parsing decision-problem Your task is to create a program that determines whether a given string is a valid regular expression or not using code snippets sourced from other sites on the StackExchange network. For the purposes of this challenge, the ...

This challenge will have you count "creatures" in the tile game Palago. A creature is any closed shape that can be formed by Palago tiles of matching colour in a hexagonal grid. The game Palago consists of tiles like this: These tiles can be rotated \$120^\circ\$, \$240^\circ\$, or not a...

Blatant rip-off of a rip-off. Go upvote those! Your task, if you wish to accept it, is to write a program/function that outputs/returns its integer input/argument. The tricky part is that if I reverse your source code, the output must be the original integer negated. Examples Let's say your so...
