Talvez deva tentar algumas variações de ortografia:
decrease river » decrease liver (Expandir a busca), decreases liver (Expandir a busca), decrease litter (Expandir a busca)
river program » writer program (Expandir a busca), linear program (Expandir a busca), higher program (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)
python c » python _ (Expandir a busca)
c python » _ python (Expandir a busca), in python (Expandir a busca), of python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease in decrease river program ) OR ( python c python python programming ))~.
