Suppose that subsets of the universe U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} are encoded by 0-1 bit strings, where a 1 in the ith-position indicates membership of the ith-th element of U. 1. Which bit string encodes the subset {2, 4, 6, 8, 10}? 2. To which subset of U does the string 1000000001 correspond? 3. To which subset of U does the string 0100111010 correspond? 4. Which bit string encodes the subset ?
