Case: Prepare 10 people's names, and then generate a random birthday for these 10 people [after 90]

1. We can find out who were born in the summer from June to August.

2. Maximum number of days longer than minimum

3. Who has the earliest birthday and who has the latest birthday?

Remarks: spring [3-5] summer [6-8] Autumn [9-11] Winter [12-2]
