WebYou can construct a bit vector in the following different ways: @tagC0 (C0) You construct an EMPTY bit vector using the following syntax: bv = BitVector (size = 0) @tagC1 (C1) 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]) @tagC2 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.
