#list_all_elements ⇒ void

This method returns an undefined value.

Lists all elements in the array with their index.

This method outputs each element of the array to the console, prefixed by its index (1-based). The index is right-justified based on the length of the array, ensuring a tidy, column-aligned output.

Example output for a 3-element array: |1| Element 1 |2| Element 2 |3| Element 3
