/* Write a program with two constant values, one with alternating binary ones and
* zeroes, with a zero in the least-significant digit, and the second, also
* alternating, with a one in the least-significant digit (hint: It's easiest to 
* use hexadecimal constants for this). Take these two values and combine them in
* all possible ways using the bitwise operators, and display the results using
* Integer.toBinaryString().
