We are given u machine units, each with a maximum production capacity of m per day.
We are also given an integer k > 1.
We have to decide if it is possible to operate the factory for atleast D days according to the following constraints:
- In any given day, the total number of gadgets produced by the u units must be atleast u * k
- Each unit has a maximum production capacity of m per day
- The total number of gadgets produced by all the units must increase every day
- The minimum number of gadgets produced by the u units must increase every day
