(#M40154181) JAVA QUESTION Keep an EYE

You have a block of platinum that can be exchanged in your bank either for cash or for smaller blocks of platinum. If you exchange a block of m grams, you get three blocks of weight m/2, m/3 and m/4 grams each. You don't get any fractional part, as the division process rounds down the value. If you exchange the block of platinum for cash, you get m units of currency. You can do any number of exchanges for smaller blocks or currency.
Given the value of a block in grams as input, write a program that would print the largest possible currency value that you can receive as the output. Assume that the maximum value of a block that can be given as an input is 1,000,000,000 grams and the minimum value is 2 grams.

(#M40152330) JAVA QUESTION Jurgensville Restaurant Puzzle: Keep an EYE

Because it is the Internet Age, but also it is a recession, the Comptroller of the town of Jurgensville has decided to publish the prices of every item on every menu of every restaurant in town, all in a single CSV file (Jurgensville is not quite up to date with modern data serialization methods).

The file's format is:

for lines that define a price for a single item:
restaurant ID, price, item_label

All restaurant IDs are integers, all item labels are underscore(no space) separated letters, and the price is a decimal number.

Because you are an expert software engineer, you decide to write a program that accepts the town's price file, and a list of item labels that someone wants to eat for dinner, and outputs the restaurant they should go to, and the total price it will cost them.
Note: Total price should be minimum price among all restaurants in the town.

If multiple restaurants are found, output any restaurant ID with the minimum price.

Please solve the puzzle above using the development language that you are being interviewed for.
