How to solve this problem??

In this question the maximum answer can be (smallest +largest)/number of cars packed (it can be less But can never be greater then this) and minimum is 1. So start with a mid value=(max+min)/2. And do binary search . If the result is true increment left and other wise decrement right . Take the maximum of the answer and this will be right then .

After doing this, do this one . Uses Binary search .This will help you
