Initially the hashtable will be empty.
Given hash function is key % 7.
1. For key 15, 15%7 = 1. So, it will be inserted at 1.
2. Next 4 is inserted at 4 (since 4%7 = 4)
3. Next element is 22. Now 22%7 = 1. But index 1 is already occupied with 15. Now separate chaining occurs. A new list will be created at the index 1 where rest of the elements with same hash value can be placed.
4. Next element is 7. 7%7 = 0. Hence it will be placed at index 0.
5. Next element is 18. 18%7 = 4. Since 4 is already occupied with element 4. Chaining occurs.
6. 21 will be placed at 0 (with chaining) since 21%7 = 0.
7. 8 will be placed at index 1 (appended in the list) since 8%7 = 1.
8. 35 too will be placed at index 0 since 35%7 = 0.
9. Now 11 will be appended at index 4 since 11%7 = 4.
10. 28 will be appended at index 0 since 28%7 = 0. (This is the final hashtable state)

Assume you are given a separate chaining hashtable where M=11. Give the final hashtable after adding keys: 24, 1, 4, 11, 12, 22, 33, 45, 8, 19, and 10. Use the hash function hash(k) = k mod 11, where k is the key. Include the main size M array with lists located at each index. Only include the key, not the hashed value, in your final table. Your table should look similar to the one below. Index List 0 [Key1,...
