Design questions¶

System design is an open-end question without a standard answer, so the key lies in the design choice for a specific question, commonly known as trade-off. This is also a question type that can better examine the knowledge level of the interviewer.

Up to now (2020-03-28), Design Questions has a total of 61 questions in LeetCode.

Among them:

• Simple 14 courses
• Medium 32 courses
• 12 difficulties

Here are a selection of 6 questions for detailed explanations, so that everyone can master the answering skills and routines of the system design questions. If you like, don't forget to like and follow.
