Talvez deva tentar algumas variações de ortografia:
sampling strategy » coping strategy (Expandir a busca), pacing strategy (Expandir a busca)
strategy case » strategy based (Expandir a busca)
java programs » and programs (Expandir a busca), care programs (Expandir a busca), java programming (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)
case java » east java (Expandir a busca), easy java (Expandir a busca), case jau (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( sampling strategy case java programs ) OR ( python code python python programming ))~.
