Understand the concept of bitwise AND, OR and XOR. Then try to visualize them. Practice in pen-paper like 23 OR 39 = ?, 67 XOR 34 = ?, 24 AND 18 = ? ..... Then try solving some bitmask problems of your level.

Additional : Watch some basic bitmask problem tutorial in YT it will make things easier for you.

Note : There is a typo in you blog. I think it will be "bitmask problems" instead of "bitmask problem" fix it otherwise it will give people wrong idea.
