Effective Data Manipulation with pandas

Assume a Series `S`. Which method can be used to reset the index in the Series?


<p>Assume a Series <code>S</code>. Which method can be used to reset the index in the Series?</p>


```python3
10    2022
20    2022
30    2022
40    2022
50    2022
```

```python3
10    2022
20    2022
30    2022
40    2022
```

```python3
10    2022
20    2023
30    2024
40    2025
50    2026
```

```python3
10    2022
20    2023
30    2024
40    2025
```

What will be the output of the following command?

```python3
S = pd.Series(2022, index = range(10, 60, 10))
```

<p>What will be the output of the following command?</p>
<pre><code class="language-python3">S = pd.Series(2022, index = range(10, 60, 10))
</code></pre>


Consider a series `S` that contains ten random numbers:

|  **index** | **marks**  |
| - | - |
|  1 |  43 |
|  2 | 30  |
|  3 | 67  |
|  4 |  10 |
|  5 |  35 |
|  6 | 19  |
|  7 |  45 |
|  8 |  61 |
|  9 | 78  |
|  10 |  12 |

Which command will give us the 4 highest numbers in ascending order?
