Greetings, I have a great doubt wish to have the most common fraction, knowing which are the numerators and denominators on a table in another.
vector <long long int> nume;
vector <long long int> deno;
DEN 1 1 1 2 1
NUM 1 2 2 5 2
Would result 3 since 1/2 can be constructed three times. You can not use decimal divide and work must be done on both vectors efficiently.
