You are given an empty hash table of size 7 that uses open addressing. The following sequence of keys is to be inserted: 15 17 8 23 35 Insert these keys using each of the following approaches. If overflow occurs, say so, and indicate the element that causes the overflow a. h(x) x % 7; linear probing ti b, h(x)-x % 7; double hashing with h2(x)-x/ 7 + 1 (using integer division) 0 2 4 6i
