Description
A cake maker wants to earn as much money as he can. Different flavors of cakes have different sizes.
For example, a chocolate cake is small and can only be cut up to 3 pieces. Vanilla cake is big and can be cut up to 20 pieces.
He has a list of prices for slices of different sizes (for each flavor of cake).
For example:
Chocolate cake:
- Price of a piece of size 1/3: 22 USD
- Price of a piece of size 2/3: 33 USD
- Price of a piece of size 3/3 (whole cake): 44 USD
| Slice | 1/3 | 2/3 | 3/3 |
| Price | 22 USD | 33 USD | 44 USD |
Vanilla cake:
- Price of a piece of size 1/20: 5 USD
- Price of a piece of size 2/20: 7 USD
- ...
- Price of a piece of size 20/20: 1090 USD
| Slice | 1/20 | 2/20 | .... | 20/20 |
| Price | 5 USD | 7 USD | .... | 1090 USD |
Given a list of prices, find the highest amount of money, the cake maker can make by cutting one cake (best cutting strategy).
For example:
The maximum earnings we can make out of the chocolate cake is 66 USD.
WHY?
All cutting strategies:
- 3 pieces of size 1/3: 22 + 22 + 22 = 66 USD
- 1 piece of 1/3 and 1 piece of 2/3: 22 + 33 = 55 USD
- 1 piece of 3/3 (whole cake): 44 USD
So the best way to cut it is into 3 pieces of size 1/3.
Help the cake maker to maximize his profit out of "one" cake!!!
