A program to solve the following problem.
You can use C, C++, C#, Java or Haskell to code your solution.

The problem
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.

Sample input 1

Sample output 1

Explanation: You can change 12 into blocks of 12/2 = 6, 12/3 = 4 and 12/4 = 3,
and then exchange these for 6 + 4 + 3 = 13 units of currencyTCS Ignite Open Lab

Sample input 2 2

Sample output 2 2

Explanation: If you exchange 2 grams into smaller blocks, it gives 2/2 = 1, 2/3 =
0, 2/4 = 0, only 1 unit. Instead, you can directly exchange the block for 2 units of

Please note that your
program SHOULD NOT print any prompts (“Please type the value of the block”)
nor any header /footer (“Block Max Value”) as part of its output.
For example, if you are asked to print out the simple interest correct to two
decimal places for a user specified values of principal, rate of interest and
number of years, then only the following statements should be there
corresponding to reading the input and printing the output:
scanf(“%d %d %d”, &principal, &rate, &years);
printf(“%8.2f\n”, principalrateyears/100.0);

Evaluated on the following parameters.
1 Compilation and linking/executing without any errors
2 Number of test cases satisfied
3 Program structure aligned to programming language (modularity for C,
OOPS compliance for C++/C#/Java and functional programming
aspects for Haskell)
4 Algorithm
5 Code clarity (variable names, indentation, visual block separation, etc)
