Given a positive integer \$N >= 3\$, output an RSA key pair (both the private and the public key) whose key length is \$N\$ bits. The RSA key generation algorithm is as follows: Choose an \$N\$-bit semiprime \$n\$. Let the prime factors of \$n\$ be \$p\$ and \$q\$. Compute \$\lambda(n) = LCM(p...

For functions \$f, g: \{0,1\}^n \rightarrow \{0,1\} \$, we say \$f \sim g\$ if there's a permutation of \$1,2,3,...,n\$ called \$i_1,i_2,i_3,...,i_n\$ so that \$f(x_1,x_2,x_3,...,x_n) = g(x_{i_1},x_{i_2},x_{i_3},...,x_{i_n})\$. Therefore, all such functions are divided in several sets such that, ...

The robber's thread is here The cops task is to write a full program that, when given an input of itself, outputs a finite deterministic string. If the program is given a different input, it should return a different output. Rules: Submissions consist of Language name If any flags are use...

The cop's thread is here The robber's task is to find a program of size equal to or less than the cop's program, which, when given an itself as input, produces the same output as the cop's program. Additionally, even if a cop's answer is provisionally marked Safe and has been revealed, you can ...

Should this identifier be suggested? code-golfdecision-problemstring Introduction In Android Studio and other IDEs there are code completions to assist efficient code insertion (especially when the names of the classes or methods are so verbose), like the one in the image below. There are sli...

Task Write a program that takes a string as input and outputs the result of the expression. Rules The input string will be worded and not numeral. There will be no parentheses. Order of calculation will be divide,multiply,subtract then add. For same operations, the calculations must be done...

Challenge Taken from here and also here An n parentheses sequence consists of n (s and n )s. A valid parentheses sequence is defined as the following: You can find a way to repeat erasing adjacent pair of parentheses "()" until it becomes empty. For example, (()) is a valid parentheses...

golfers! This challenge is about finding the smallest disk that contains some given points. This is made somewhat tricker, however, by the fact that in this challenge, the disk's coordinates and radius must both be integers. Your input will be a list of points with integer coordinates x and y. Y...

Given an input integer n > 1, output an ASCII-art octagon with side lengths composed of n characters. See examples below: n=2 ## # # # # ## n=3 ### # # # # # # # # # # ### n=4 #### # # # # # # # # # # # # # # # # ...

Name: Create a Programming Language Tags: code-bowling, and cops-and-robbers Cops: The cops must design a programming language that takes in the contents of the program from a default I/O method, and do something. Rules: The program must not print anything to STDERR The program must be able...

The 5-card magic trick involves a magician whose assistant gives them 4 shown cards and a hidden one, in this order, and the magician must guess the hidden one. WARNING: Solution below! Leave now or get spoiled with it. The solution The trick here is that the five cards are given in a specif...
