Shell Programming and Scripting

Can such Puzzle solve through UNIX script? if yes, what could be the code?
This has been solve in C language. we were trying to solve this through shell but could not because of not able to pass 1st argument with multiple value. we are not expert in unix scripting. Below is the puzzle

John is a papaya merchant. He visits different papaya orchards and collects papayas from farmers in the fruit containers. Each farmer could provide different quantity of papayas. John is smart and labels the number of papayas collected in each container. All the containers are of the same size and capacity.

At the end of the day, when John returns from this fruit collection tour, he has to ensure that all the containers carry same number of papayas so that they can be subsequently shipped to his various distribution channels. It is important to equi-distribute the number of papayas in each container for efficient logistics and keep his distributors happy.

The question is – Given n containers with different number of papayas say q1, q2,..qn in each container, how many papayas will John have to move and what is the least possible number of moves it will take him to ensure that papayas are equally distributed. Obviously, he is tired from his day long work and he would prefer to move minimum possible papayas in least number of moves. (one move consists of transferring any number of papayas from one container to another one)

The input consists of number of papayas in each container separated by space.

Expected Output : Number of papayas moved and number of moves. (if it is not possible to equally distribute the papayas, then the output should be -1)

Code:

Example1

Command line program Input: 2 1 4 3 5

Program output: papayas:3 Moves: 2

Explanation:

John opens container with 5 papayas and moves 2 papayas to container that originally had 1 papaya.  (move 1)
He opens container with 4 papayas and moves 1 papaya to container that originally had 2 papayas. (move 2)

Code:

Example2

Input: 2 1 4 3

Output: -1

Explanation:

Since there are total of 10 papayas and 4 containers, it is not possible to equally distribute the papayas in all containers.

code tags please, not HTML

Anything that can be solved by an algorithm can be implemented by any Turing complete programming language, which the shell certainly is.

Please show the algorithm already used or its C implementation.

Sounds very much like homework.

Thanks Sea for your update.
I am trying to remove this thread from this forum but not seeing any option.
I will start this thread as suggested by you.
