tryalgo 1.4.0

Algorithms and data structures for preparing programming competitions

Algorithmic Problem Solving

Algorithms and data structures for preparing programming competitions (e.g. ICPC, see more) and coding interviews.
By Christoph Dürr and Jill-Jênn Vie.

Our book is available in French, English, Simplified and Traditional Chinese.

Install

pip install tryalgo

Documentation

• Documentation of tryalgo 1.4
• Blog tryalgo.org in French and English

Demo: TryAlgo in Paris

Shortest paths on the graph of Paris.

To run it yourself:

pip install -r examples/requirements.txt
jupyter notebook  # Then go to examples folder

Usage

Dynamic programming some example with coin change:

from tryalgo import coin_change

print(coin_change([3, 5, 11], 29))  # True because 29 = 6 x 3 + 0 x 5 + 1 x 11

Des chiffres et des lettres (that inspired Countdown)

from tryalgo.arithm_expr_target import arithm_expr_target

arithm_expr_target([25, 50, 75, 100, 3, 6], 952)

Returns '((((75*3)*(100+6))-50)/25)=952'.

Tests

All algorithms are thoroughly tested. These tests can be used to practice your programming skills!

python -m unittest

Most snippets from the book are within 76 columns (French version) or 75 columns (English version, to be released soon).

Our code is checked:

make pycodestyle  # PEP8
make pylint
