Talvez deva tentar algumas variações de ortografia:
lines programming » line programming (Expandir a busca), linear programming (Expandir a busca), lineal programming (Expandir a busca)
coder separation » cover separation (Expandir a busca), modern separation (Expandir a busca), center separation (Expandir a busca)
separation lines » separation plants (Expandir a busca), separation in (Expandir a busca), separation des (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder separation lines programming ) OR ( in python python python programming ))~.
