Explain what the KISS principle means in software development

The KISS principle (Keep It Simple, Stupid) in software development means that solutions and code should be as simple and understandable as possible. Complexity should be avoided unless justified.

Applying the KISS principle helps to:

• Reduce the number of errors and bugs.
• Make support and development of the code easier.
• Improve readability and understanding by other developers.

Example: instead of complex nested conditions, it is better to use simple functions with clear names, and instead of bulky structures, more obvious and concise solutions.
