Write a Function in F# please and Thankyou.
![**Exercise #05: pairwise L1 L2**
---
**Objective:**
The task is to write a function named `pairwise` that takes two lists, `L1` and `L2`. Both lists must have the same length. The function should combine the corresponding elements from each list into pairs and return a list of these pairs.
**Example:**
For input lists:
- `L1 = [1; 3; 5; 7]`
- `L2 = [10; 20; 30; 40]`
The function should produce the output:
- `[(1,10); (3,20); (5,30); (7,40)]`
**Instructions:**
- You may solve the problem by using recursion, employing higher-order functions, or both.
- Tail recursion is not a necessary requirement for this exercise.
**Starting Template:**
```ocaml
let rec pairwise L1 L2 =
[]
```
---
**Note:** The exercise illustrates how to merge two lists by using functional programming techniques, emphasizing various approaches like recursion or higher-order functions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F672bf286-8abe-4b07-9ca1-0d5b2612956c%2F60f18ea5-ebb3-4f6e-a7d8-56bb1d72d98a%2F1gr6s95_processed.png&w=3840&q=75)
