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

pip install tryalgo

• Documentation of tryalgo 1.3
• Blog tryalgo.org in French and English

Shortest paths on the graph of Paris.

To run it yourself:

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

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'.

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

python -m unittest
