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.

pip install tryalgo

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

Shortest paths on the graph of Paris.

To run it yourself:

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

Dynamic programming some example with coin change:

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

Des chiffres et des lettres (that inspiredCountdown)

fromtryalgo.arithm_expr_targetimportarithm_expr_targetarithm_expr_target([25,50,75,100,3,6],952)

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

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