Talvez deva tentar algumas variações de ortografia:
fractional problems » functional problems (Expandir a busca), practical problems (Expandir a busca), variational problems (Expandir a busca)
coder fractional » order fractional (Expandir a busca), power fractional (Expandir a busca), model fractional (Expandir a busca)
coding python » codigo python (Expandir a busca), codigos python (Expandir a busca), using python (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
using coding » using coping (Expandir a busca), using coating (Expandir a busca), using cooking (Expandir a busca)
problems on » problems in (Expandir a busca), problems of (Expandir a busca), problems and (Expandir a busca)
on array » an array (Expandir a busca), dna array (Expandir a busca), _ array (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder fractional problems on array ) OR ( using coding python python programming ))~.
