I have to make a pair like as we input 4 6 12. The pair will be (4,3),(3,4),(2,6) so 3 pairs so plz make a program but with input n,m, k in 10^10?
In MySQL, if I am looking to match with a list of numbers, eg, select * from t where id in (1,2,3,4,5,6). Is there any optimization to tell the db that my inputs are in order?
