add: Adding is the opposite of removing; it involves inserting elements into a data structure. Just as removing lightens your backpack by taking things out, adding fills it up by putting things in.
data structures: Data structures are containers that hold and organize data efficiently. They can be compared to different types of storage units such as backpacks or suitcases that store various items.
deletion: Deletion is another term for removing, specifically referring to the action of erasing or eliminating an element from a data structure. It's like crossing out a task on your to-do list once it's completed.
