The title is "one interview question with a monthly salary of 30 thousand". In fact, it is not that you can answer the question (because I answered it, but not ). The test logic and reasoning capabilities are good.

Mr. Zhang told James about M, mr. Zhang told Xiaoqiang about the N value and asked them if they knew his birthday was that day?
