BRIEF INTRODUCTION The code below does basic operations with Big Integer Numbers, or what is the same, with multi-digit integers. These basic operations are: adding and multiplying. In order to represent a Big Integer Number we will use an unsigned char array (can be changed) in which every posi...

Check my Knight's Tour Given as input an n-by-n matrix of integers, check that all integers from 1 to n² are present, and that all pairs of consecutive integers are exactly a Knight's move apart. (For instance, a 4-by-4 board with the values 1 2 1 2, 2 1 2 1, 1 2 1 2, 2 1 2 1 would meet the cond...

Euler's Theorem in Geometry geometry code-golf If everything goes well, this challenge will be posted on April 14 00:00 utc-12 Today (or tomorrow, depending on your timezone, by the time of posting) is the birthday of the great mathematican and physicist Leonhard Euler. To celebrate his birthda...

We have given length of array and we have to find number of arrays can be created by these conditions : 1. Elements in array can be from 0 to 5 inclusive. 2. Xor of all elements is 0. Explaination : input: 2 O/p: 6 i.e 00,11,22,33,44,55

This puzzle looks a little bit fun because there are six e's to print. No input. Print this: Where there is a will, there is a way. Including the space bar and punctuations. Excluding the newline at the end. Do not use the strings Where there is a will or way in the source. Note: We use code...

Here's an interview question I've seen on a few sites. People claim that an O(n) solution is possible, but I've been racking my brain these last 2 days and I couldn't come up with a solution, nor find one anywhere on the web. Given an array of integers, find two disjoint, contiguous subarrays su...

A very simple challenge today. Output a truthy value whether the ASCII character (or it's code) supplied is a brainfuck instruction (one of +-,.<>[]), and a falsy value if it's a comment (everything else). Input + # < > . P , Output true false true true true false true

Inspired by this glove-themed 538 Riddler Express Puzzle. Task You are given a positive integer n, and a list A = [a_1, a_2, ..., a_k] of k distinct positive integers. Then a restricted composition is an ordered list P = [p_1, p_2, ..., p_m] where each p_i is a (not necessarily distinct) membe...
