• i is a variable used to access elements in an array.

• It starts at 0 for the first element and increments by 1 for each subsequent element.

• For example, in the array ['apple', 'banana', 'orange'], i=0 would refer to 'apple', i=1 to 'banana', and i=2 to 'orange'.

Genetically modified organisms (GMOs) are organisms whose genetic material has been altered in a way that does not occur naturally.

• GMOs are created by inserting genes from one organism into another to give it a desired trait.

• They are commonly used in agriculture to create crops that are resistant to pests or herbicides.

• GMOs have been a controversial topic due to concerns about their safety and potential impact on the environment.

A linked list is a data structure consisting of nodes where each node contains a data field and a reference to the next node.

• Consists of nodes connected by pointers/references

• Does not have a fixed size like an array

• Can easily insert or delete elements without shifting other elements

• Example: Singly linked list, Doubly linked list

Polymorphism is the ability of a single function or method to operate on different types of data.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.

Bubble Sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order.

• Initialize an array of strings to be sorted

• Repeat until no swaps are needed: Compare adjacent elements and swap if necessary

• Continue until the array is sorted in ascending order
