Beginner's Problems

these tasks are recommended for those who only started learning and want exercises
on implementation  they usually do not require inventing tricky algorithm or applying
special knowledge

Simple Mathematics

programming exercises slightly related to math  they may help you in learning basics
of cryptography, financial calculations etc

Geometry Basics

here are problems about geometry in 2D euclidean space (i.e. plane)  only basic
understanding of the topic is required since the goal is to help learning popular
geometryrelated algorithms

Simple Puzzles

here are problems for which you are supposed to spend some time scratching your head,
before you can solve and implement them  they usually have no stepbystep explanation
to avoid spoiling the joy of solving :)

String Tricks

exercises about basic operations on strings and some more advanced algorithms
of textprocessing

Game Logic

here we collect general tasks arising while programming simple and advanced games 
hope they may inspire you to write some funny applications

Graph Algorithms

among the lot of programming problems on graphs we select some simplest or most general
to give the idea of what it looks like, i.e. to introduce these data structures to you

Physics and Modelling

as many games and scientific researches require precise modelling of certain processes
we include few such problems along with explanations how to approach them

Popular Algorithms

these are about implementation of popular algorithms, ranging from some special data
structures to cryptography and compression

Advanced Math

it is wise to try this if you have found "Simple Math" exercises too simple :)

Challenges

problems of special kind  they could be solved better or worse and you gain more or
less extra points depending on this

Interactive Problems

another special kind of problems  you are to "play a game" against the remote server
and win it in order to score the points

Brainfuck Puzzles

these exercises should be solved in Brainfuck language  regard them as
programmer's toys rather than serious problems (though they may require you to spend
significant time)

Intel 4004 Assembly

these exercises should be solved in specific Assembly language (we start with
asm for Intel 4004 cpu)  the goal is to introduce such a lowlevel programming and
certain specific algorithms to you
