Cyclically Sort a List
Given a list of Integers greater than zero, Sort each of the unique values in ascending order, then repeat the process on the remaining duplicate values and append.
Construct the Constructability sequence
Consider compass-and-straightedge construction, where you can construct new points from existing ones by examining intersections of straight lines and circles ...
Sub-quadratic base conversion
Write a program that converts a positive integer given in base 10 to its base 2 representation.
Your algorithm must run in a complexity lower that \$O(n^2)\$
Compute the Kimberling Sequence
The Kimberling Seqeunce is a sequence of sequences.
Each sequence is defined in terms of the previous sequence and the previous stage number.
Create a sorting algorithm in as few bytes as possible. It can be, at worst, \$ O(n^2) \$. This can be insertion sort, mergesort, quicksort, or any other sorting algorithm with \$O(n^2)\$ ...
Given two arrays, let's call them a and b, and a number n, your task is to see if there exists a subarray in a so that that subarray's sum is n and there is a subarray in b that also sums to n ...
