Data structure operations

When working with most data structures, you’ll typically perform four operations:

• Read: You want to look up some data at a particular point in the data structure (e.g., look up the value at index 4 of an array).
• Search: You want to find a value within the data structure (e.g., find the value “foo” within an array).
• Insert: You want to add a value to the data structure.
• Delete: You want to remove a value from the data structure.
