Return min(q1,min(q2,q3)

#1

please explain why are we returing the this statement return min(q1,min(q2,q3)

#2

Hi Ayush, q1 q2 and q3 represent the answers for 3 different ways of reducing N to 1. we need to choose the minimum of these three ways.

so if N = 30 and if you divide it by 3 let us say q1 steps will be needed for 10, if you divide it by 2 then q2 steps will be needed for 15 and if you subtract 1 from it q3 steps will be needed for 29. you will choose the way in which the steps needed to reach 1 are minimum. that is what the statement min(q1,min(q2,q3) helps you to do.

Hope that helps :slight_smile:
