Quick implementation of Galois fields
View galois.c
/*
* The following is an implementation of the finite field GF(2^8) as bit vectors of length 8, where the nth bit represents the
* coefficient of the nth power of the generator in each element, and the generator satisfies the minimal polynomial
* x^8 + x^4 + x ^3 + x^2 + 1 in the prime field Z_2, in which addition is equivalent to XOR and multiplication to AND.
* The elements of GF(2^8) thus represent polynomials of degree < 8 in the generator x. Addition in this field is simply
* bitwise XOR, but multiplication requires the elimination of powers of x <= 8.

Telegram chat backup/export
View 0.README.md

How to use

  1. Login to https://web.telegram.org
  2. Copy-paste contents of telegram-scripts.js into JS console
  3. Run showContacts() to get the list of contacts with ids
  4. Run saveChat(userId) where userId is the id from step 3

Process can take a while, check console for progress. Occasionall FLOOD_WAIT errors are expected. Once done, browser will download the JSON file.

Disclaimer: I have no idea if this are indeed the correct answers. I just solved the exercises like this. I think that they are right though.

I have added my own code to this gist. It is ugly as hell, just like you can expect from code created in a contest like this.

Beautiful Strings

Difficulty: easy

It is simple to see that a greedy solution is good enough.
