+The numbers formed by adding one to the products of the smallest primes are
+called the Euclid Numbers (see wiki). Write a script that finds the smallest
+Euclid Number that is not prime. This challenge was proposed by Laurent
+Rosenfeld..

+You are given two 2-D array of positive integers, $items1 and $items2 where
+element is pair of (item_id, item_quantity).

+Write a script to return the merged items.
