Talvez deva tentar algumas variações de ortografia:
lands problems » and problems (Expandir a busca), andes problems (Expandir a busca), land problem (Expandir a busca)
decoder based » recorder based (Expandir a busca), disorder based (Expandir a busca), decoder faster (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
based binary » based ternary (Expandir a busca), based binders (Expandir a busca), and binary (Expandir a busca)
binary lands » binary blends (Expandir a busca), binary and (Expandir a busca), binary fluids (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: (( decoder based binary lands problems ) OR ( in python python python programming ))~.
