Talvez deva tentar algumas variações de ortografia:
by programming » by reprogramming (Expandir a busca), _ programming (Expandir a busca), c programming (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder arrays » cdna arrays (Expandir a busca), fiber arrays (Expandir a busca), solar arrays (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
arrays by » arrays _ (Expandir a busca), arrays of (Expandir a busca), arrays in (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder arrays by programming ) OR ( _ python python python programming ))~.
