Question

How would the table look like if we used separate chaining (open hashing)

### Problem Statement

Insert the following keys using separate chaining (open hashing) in the hash table below:

- T0001235
- T0101405
- T0131735
- T0001038
- T0201230
- T0807000
- T0201203
- T2374005
- T4070745
- T4072307

### Hash Table Structure

#### Table of 23 Elements

- **Index 0:** `nullptr`
- **Index 1:** `nullptr` → T20107424
- **Index 2:** `nullptr`
- **Index 3:** `nullptr`
- **Index 4:** `nullptr` → T3290334 → T0000284
- **Index 5:** `nullptr`
- **Index 6:** `nullptr` → T0314303
- **Index 7:** `nullptr`
- **Index 8:** and so on (`etc.`)
- **Index 21:** `nullptr`
- **Index 22:** `nullptr`

### Diagram Explanation

The diagram illustrates a hash table using separate chaining, where collisions are handled by linking elements in a list. Each index in the table has either `nullptr` for empty slots or a linked structure showing the keys stored at that index. For example, at index 4, two keys are chained: T3290334 and T0000284. Using open hashing, multiple keys can be stored at the same index without overwriting.
