If universal set U=`{0,1,2,3,4,5,6,7}, A={2,3,7}, B={4,6} and C={0,2,4,6}`. Find the following
(i) `A cap phi`
(ii) `B' cap C`
(iii) `A' cap C`
(iv) `A cap A'`

Explanation

Let's solve the given problem step by step.

### Given:
- Universal set \( U = \{0, 1, 2, 3, 4, 5, 6, 7\} \)
- Set \( A = \{2, 3, 7\} \)
- Set \( B = \{4, 6\} \)
- Set \( C = \{0, 2, 4, 6\} \)
