Describe the process of deleting an element from a specific position in an array using swapping.

To delete an element from a specific position in an array using swapping, the following steps can be followed:

1. Determine the position of the element to be deleted in the array. Let's assume the position is 'pos'.

2. Check if the position is valid, i.e., it should be within the bounds of the array. If the position is less than 0 or greater than or equal to the length of the array, then it is an invalid position.

3. If the position is valid, perform the swapping operation. Swap the element at the specified position with the last element of the array.

- Store the value of the element at the specified position in a temporary variable.
- Assign the value of the last element of the array to the element at the specified position.
- Assign the value of the temporary variable to the last element of the array.

This swapping operation effectively moves the element to be deleted to the end of the array.

4. After swapping, decrement the length of the array by 1 to indicate that the element has been deleted.

- If the array is implemented using a fixed-size array, the length variable can be used to keep track of the number of elements in the array.
- If the array is implemented using a dynamic array or a resizable array, the length variable can be updated accordingly.

5. The element to be deleted is now at the end of the array. To remove it completely from the array, resize the array by creating a new array with a length of (original length - 1).

- If the array is implemented using a fixed-size array, create a new array of size (original length - 1) and copy all elements from the original array to the new array, excluding the last element.
- If the array is implemented using a dynamic array or a resizable array, the resizing operation can be handled internally by the data structure.

6. Finally, update the reference to the array to point to the newly resized array, effectively removing the element from the specified position.

It is important to note that this swapping-based deletion process has a time complexity of O(1) for accessing and swapping the elements, but it may have a time complexity of O(n) for resizing the array if required.
