$2.$ Write the pseudocode. $(15$ points$)$

$$ The parent creates $10$ child processes through fork.

$$ The parent sends a unique code to each child through pipe. The codes are stored in an array $$int codes$[10].$ The first element in the array is send to the first child, the second to the second child and so on$.$

In your pseudocode, you must $(1)$ clearly define the file descriptors, $(2)$ clearly define the first parameter and the second parameter in read$/$write$.($Hint: remember to call wait in parent to synchronize parent and child$).$
