What is the time complexity of inserting an element at a specific position in an array using swapping?

The time complexity of inserting an element at a specific position in an array using swapping depends on the position at which the element is being inserted.

If the element is being inserted at the beginning of the array (position 0), the time complexity would be O(n), where n is the number of elements in the array. This is because when inserting at the beginning, all the existing elements need to be shifted one position to the right to make space for the new element. This shifting operation requires iterating through all the elements in the array, resulting in a linear time complexity.

If the element is being inserted at any other position in the array (position i, where i > 0), the time complexity would also be O(n). This is because the swapping operation involves swapping the new element with the element at the desired position, and then swapping the subsequent elements until the new element reaches its correct position. Again, this requires iterating through all the elements in the array, resulting in a linear time complexity.

In summary, the time complexity of inserting an element at a specific position in an array using swapping is O(n), where n is the number of elements in the array.
