Talvez deva tentar algumas variações de ortografia:
duration programming » education programming (Expandir a busca), creation programming (Expandir a busca), educational programming (Expandir a busca)
maximum duration » maximum ratio (Expandir a busca), maximum adsorption (Expandir a busca), maximum phonation (Expandir a busca)
coder maximum » model maximum (Expandir a busca), shower maximum (Expandir a busca), models maximum (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)

Você pode obter mais resultados ajustando o argumento de busca.

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