WebMethod 1: Using bitwise operation : Let’s take a look at the binary representation of 0 to 16. The rows with star marked are the rows for the power of 2. As you can see here, if a number is n power of 2, its binary representation will be 1 followed by n times 0. For example, 16 is 2 to the power 4. So, its binary representation is 10000 or 1 ...
