Can someone please explain it to me ASAP?!!! This is quadratic hashing
### Quadratic Probing in Hash Tables

#### Jump to Level 1

**Hash Table Visualization:**
- **valsTable:**

| Index | Value | Status                |
|-------|-------|-----------------------|
| 0     |       | Empty-since-start     |
| 1     |       | Empty-since-start     |
| 2     |       | Empty-since-start     |
| 3     |       | Empty-since-start     |
| 4     |       | 60                    |
| 5     |       | Empty-since-start     |
| 6     |       | Empty-since-start     |
| 7     |       | Empty-since-start     |
| 8     |       | 20                    |
| 9     |       | Empty-since-start     |
| 10    |       | Empty-since-start     |

**Status Legend:**
- **Empty-since-start:** `Light Blue`
- **Empty-after-removal:** `Orange`
- **Occupied:** `Red`

Hash table `valsTable` uses quadratic probing, with a hash function of `key % 11`, and coefficients `c1 = 1`, `c2 = 1`.

**Problem Statement:**
What is the specific sequence of buckets probed by `HashRemove(valsTable, 80)`?

Example: `1, 2, 3` (commas between values)

*[Input Box for Answer]*
*[Check Button]*
*[Next Button]*

### Explanation:
Hash functions and probing sequences are fundamental concepts in understanding hash tables. In quadratic probing, the position for rehashing is determined by initially hashing to a position and then probing quadratically further positions if a collision occurs, i.e., positions of the form `(hash + c1*i + c2*i^2) % table_size`.

In this particular exercise, you are asked to determine which bucket positions are probed when trying to remove the value `80` from the hash table using the given quadratic probing settings.
