This repository has solutions to some problems of Project Euler.
Problems are sorted by their number of solutions and are made predominantly in R but also in Python, Julia and Scala.
Simplicity, memory efficiency, speed optimization are favoured and - as much as possible - only built-in functions are used.
R doesn’t support large integers and for this I had to use the package gmp.
build_headers.Rcreates files for the intended language with headers that contain information about the problem (problem number, title, url and description). There are two user-defined arguments:- problem number range (ex: 51:53 for R creates files p51.R, p52.R and p53.R)
- language (R, Python, Julia, Scala).
sorts_problems.Rsorts problems by their number of solutions; in descending order. This is useful to see that people don't work in these problems sequentially.
