+Task 1: Bitwise OR
+Submitted by: Mohammad Sajid Anwar
+
+You are given an array of positive integers, @ints.
+
+Write a script to find out if it is possible to select two or more elements of 
+the given array such that the bitwise OR of the selected elements has atlest one 
+trailing zero in its binary representation.

+Task 2: Distribute Elements
+Submitted by: Mohammad Sajid Anwar
+
+You are given an array of distinct integers, @ints.
+
+Write a script to distribute the elements as described below:
+
+1) Put the 1st element of the given array to a new array @arr1.
+2) Put the 2nd element of the given array to a new array @arr2.
+
+Once you have one element in each arrays, @arr1 and @arr2, then follow the rule below:
+
+If the last element of the array @arr1 is greater than the last
+element of the array @arr2 then add the first element of the
+given array to @arr1 otherwise to the array @arr2.
+
+When done distribution, return the concatenated arrays. @arr1 and @arr2.
