Converting to decimal before converting to binary isn't ideal. We should have the algorithm convert directly from octal to binary, because otherwise this isn't much better than just using the existing octal-to-decimal and decimal-to-binary conversion files.

This is still converting from octal to decimal to binary. int converts the input from octal to decimal, and bin converts that value from decimal to binary.
