Hash Table

A hash table also called a hash map, is a data structure that maps key-value pairs. The hash table can be used in complex systems to provide fast access and compact storage. A hash table is a structure that stores data in an abstract data type kind of associative array. It keeps data in an array format, with a distinct index value for every data value. If the index of the required data is known, then the data can be accessed very easily.

Question

### Jump to Level 1

**Hash Table Example (valsTable)**

A hash table `valsTable` is displayed below, utilizing the hash function `key % 5`.

#### Hash Table Structure:
```
valsTable:
0 -> [5] -> [20] -> [45]
1 ->
2 -> [32] -> [47]
3 -> [13] -> [33] -> [43]
4 -> [9] -> [14] -> [24] -> [39]
```

#### Explanation:
- **Index 0**: Contains the linked list `[5] -> [20] -> [45]`.
- **Index 1**: Empty.
- **Index 2**: Contains the linked list `[32] -> [47]`.
- **Index 3**: Contains the linked list `[13] -> [33] -> [43]`.
- **Index 4**: Contains the linked list `[9] -> [14] -> [24] -> [39]`.

### ListSearch Comparison Tasks

Determine how many comparisons the `ListSearch` function performs to find specific items in `valsTable`.

**Questions:**
1. **If item 33 is in valsTable?**
- You need to find the number of comparisons to locate `33`.

2. **If item 19 is in valsTable?**
- You need to find the number of comparisons to determine that `19` is not in `valsTable`.

3. **If item 32 is in valsTable?**
- You need to find the number of comparisons to locate `32`.

**Example:**
- If `item 33` is searched within `valsTable`, the function might perform comparisons and you would input the number, e.g., `Ex: 10`.

**Input Fields:**
- For 33: `[ ]`
- For 19: `[ ]`
- For 32: `[ ]`
