Suppose that the universal set is $,$

$5,6,7,8,9,10.$ Express each of these sets with bit

strings where the $i$ th bit in the string is $1$ if $i$ is in the

set and $0$ otherwise.

a$)\{3,4,5\}$

b$)\{1,3,6,10\}$

c$)\{2,3,4,7,8,9\}$

Using the same universal set as in the last problem, find

the set specified by each of these bit strings.

a$)1111001111$

b$)0101111000$

c$)1000000001$
