(Linear Search) Often, we are given a list of unsorted numbers and we would like to search for a given value, starting from the front of the list and stopping when we find the first instance. This is called linear search. lin_search Function: Input variables: • a vector of unsorted numbers representing the data to search • a scalar representing the item we wish to find Output variables: • a scalar representing the first location in the vector where the item was found; if the item is not found, return a -1 A possible sample case is: » loc = lin_search([1 1 4 2 3 5 2 3 4 5], 3) loc = 5 » loc = lin_search([1 1 4 2 3 5 2 3 4 5], 6) loc -1

create a code 

**(Linear Search)** Often, we are given a list of unsorted numbers and we would like to search for a given value, starting from the front of the list and stopping when we find the first instance. This is called linear search.

**lin_search Function:**

- **Input variables:**
  - A vector of unsorted numbers representing the data to search
  - A scalar representing the item we wish to find

- **Output variables:**
  - A scalar representing the first location in the vector where the item was found; if the item is not found, return a -1

A possible sample case is:

```plaintext
>> loc = lin_search([1 4 2 3 5 2 3 4 5], 3)
loc = 5

>> loc = lin_search([1 4 2 3 5 2 3 4 5], 6)
loc = -1
```
