Web1. Bit Vector In this approach, the free space list is implemented as a bit map vector. It contains the number of bits where each bit represents each block. If the block is empty then the bit is 1 otherwise it is 0. Initially all the blocks are empty therefore each bit in the bit map vector contains 1. WebYou can construct a bit vector in six different ways. (1) You can construct a bit vector directly from either a tuple or a list of bits, as in bv = BitVector( bitlist = [1,0,1,0,0,1,0,1,0,0,1,0,1,0,0,1] ) (2) You can construct a bit vector from an integer by bv = BitVector( intVal = 56789 ) The bits stored now will correspond to the binary
