## Overview

In Euphoria, the **`patch()` method** is used to pad up a sequence to a required length and from a specified position.

To patch a sequence, we have to provide the sequence to be patched, the value we want to pad it with, and specify the index from where we want the patch to begin. Additionally, we'll have to indicate what we'd use to fill up extra spaces before the padding starts.

The diagram below is a pictorial representation of how `patch()` works. It will also replace any character that is at the position it wants to patch.

## Syntax
```
patch(toBePatched,patchWith,startAt,filler)
```
## Parameters
* **`toBePatched`**: This is the sequence we want to pad up.
* **`patchWith`**: This will pad up the provided sequence.
* **`startAt` :** The position to start the sequence patching from.
* **`filler`**: This is used to pad up extra space or gaps that were not patched. This is possible if the `start` value is more than the `toBePatched` value. Its default value is `" "` if we do not provide it. It is an object data type.

## Return value
This method returns a sliced sequence, such as `toBePatched`.

   
> Note: In order to use this method, we have to include the `sequence.e` file in our program, which is part of the standard library of the language.
## Example




include std/sequence.e

--declare variables
sequence toBePatched1, toBePatched2, results1, results2

--assigning values
toBePatched1 = "This sequence will be patch at index10"
toBePatched2 = "Work Out"

results1 = patch(toBePatched1,"ed wholly at \n",28 )
results2 = patch(toBePatched2, "ing ", 5,6)

printf(1,"value of result1: %s", {results1})
printf(1, "value of result2: %s", {results2})



## Explanation

* **Line 2 :** We include the `sequence.e` file from standard library `std`.
* **Line 4:** We declare a few varibles of `sequence` type.

* **Lines 8–9**: We assign values to some of the declared variables.

* **Lines 11–12**: We assign values of the variables `results1` and `results2` to the output of the `patch()` method on the earlier defined variables.
* **Lines 14–15**: We print the output to the screen.

What is the patch() method in Euphoria?

The patch() method in Euphoria pads a sequence to a specified length from a start position, replacing existing characters if necessary.
