Is that possible to have a ranking of the solutions based on their performing time? I think that the could be a method that is fast even if more sized.
provides inexpensive method. There is only one 2nd order polynomial solution and one division.
i get the same solution but the test says false
for test 9, 11
I thought we had to discount all the equivalent fractions (like 2/2) so I wrote this horrible cheat. How embarrassing.
