这个问题应该从哪个方向入手？

Question

共有32只球队
欧洲：法国、西班牙、波兰、丹麦、荷兰、德国、威尔士、英格兰、比利时、塞尔维亚、克罗地 亚、瑞士、葡萄牙
亚洲：中国、伊朗、澳大利亚、沙特、日本、韩国
南美洲：巴西、厄瓜多尔、阿根廷、乌拉圭
中北美及加勒比：美国、哥斯达黎加、加拿大、墨西哥
非洲：加纳队、突尼斯队、摩洛哥队、塞内加尔队、喀麦隆队
其中第一档球队分别是：法国、西班牙、德国、英格兰、葡萄牙、巴西、阿根廷、荷兰
第二档球队是： 波兰、丹麦、比利时、中国、喀麦隆、乌拉圭、日本、克罗地亚
现在分组规则如下：
●共分8个组，分别：A组B组C组D组E组F组G组H组
●每组只能有一支第一档球队，只能有一只第二档球队；
●每组一共有四支球队。非第一档、非第二档球队随机进行某一组
●小组积分前两名出线，开始淘汰赛
●出线后对阵图如下：后面CD /EF/ GH类似对阵
【可以参考2022年卡塔尔世界杯规则：

请编写程序：完成年中国世界杯的赛事编排，要求如下：
1、显示各小组分组情况
2、显示总共有多少场比赛场次
3、设计方法：判断中国队会遇到巴西队吗?如果遇到是什么时候碰到[小组赛、1/8.
1/4、半决赛、决赛]?
