Because all the bit positions in the preceeding problem contain 1s, the simplest approach to completing the conversion for the above problem would be to:
A) determine the number of bits, raise 2 to that value and then subtract 1.
B) determine the weight of the MSB and add 1 to that value.
C) determine the weight of each of the bit positions and sum the results.
D) simply determine the weight of the MSB.

The simplest way to find the value when all bits are 1s is to calculate 2 raised to the number of bits (which gives the value of the next higher bit position) and then subtract 1. This gives the maximum value for the current number of bits.
