Test easy–medium array/string tasks
Problem: Demonstrating Robust Test Case Generation for Algorithmic Problems
This exercise assesses your ability to systematically identify and articulate critical test cases for typical easy-to-medium array and string manipulation problems. You are expected to demonstrate a practical approach to transforming a general understanding of edge cases into concrete test inputs and their corresponding expected outputs, suitable for rapid application during an online coding assessment.
Consider the following categories of edge cases:
- Empty or null inputs
- Single-element inputs
- Inputs with duplicate values
- Inputs where all values are identical
- Inputs that are already sorted or in reverse order
- Inputs involving extreme numeric ranges (e.g.,
MIN_INT,MAX_INT, zero, negative numbers) - Inputs containing Unicode or multibyte characters (for string problems)
- Very large inputs (to test performance and memory limits)
