Discussion

Coconut is Captain Gangplank’s favourite fruit. That is why he needs to drink coconut
juice from b coconuts each day.
On his next trip, he would pass through N citis.
His trip would begin in the 1-st city and end in the N-th city.
The journey from the i-th city to the (i + 1)-th city costs D days.
Initially, there is no coconut on his ship. Fortunately, he could get supply of C coconuts
from the i-th city.
Could you tell him, whether he could drink coconut juice every day during the trip no
not?
