WebProperty: As we know that when all the bits of a number N are 1, then N must be equal to the 2 i-1 , where i is the number of bits in N. Example: Let’s say binary form of a N is {1111} 2 which is equal to 15. 15 = 2 4-1, where 4 is the number of bits in N. This property can be used to find the largest power of 2 less than or equal to N. How?
