Data Structure Purpose?

To organize and store data for efficient access and manipulation.

Algorithm Goal?

To solve a specific problem or perform a particular task.

Stack vs. Queue?

Stack: LIFO (Last-In-First-Out). Queue: FIFO (First-In-First-Out).

Linear Search Time Complexity?

O(n), meaning the time grows linearly with the input size.
