Traverse
Definition
Traversing refers to the process of accessing each element in a data structure (such as arrays or linked lists) one by one, usually for performing some operation on them.
Analogy
Imagine you are walking through every room in your house to check if all the lights are turned off. Similarly, traversing allows us to visit each element in a data structure systematically.
Related terms
Iteration/Looping: Repeating a set of instructions multiple times until certain conditions are met.
Searching: The process of finding a specific element within a data structure.
Sorting: Rearranging the elements in a specific order within a data structure.
