Interview Course Based on Story Questions

# Problem statement

You are provided with a sorted array of integers, and you have to find the $kth$ missing number in that array.

> **NOTE:** The missing number can also exist beyond the provided sorted array.

## Input

The input will be an array of integers and an integer value `k`. The following is an example input:

```python
[4,7,9,10], 1
```

## Output

The output should be the $kth$ missing number from the array. The following is just an example output:

```
5
```

In the above case, `k=1`. Therefore, the first missing value in the array is **5**.

# Coding exercise

You need to implement the function `missing_element(arr, k)` where `arr` is the sorted array and `k` is the required missing number that you want to find. The function returns a single integer value representing the $kth$ missing number in the array.
