【pwn】[HGAME 2023 week1]choose_the_seat --数组越界，劫持got表
查一下程序保护情况 发现是partial relro，说明got表是可以修改的，下一步看代码逻辑 看到这一段 puts(&seats[16 * v0]);存在数组越界的漏洞，因为上面的代码没有对v0进行负数的限制，v0可以是负数，我们来看一下seat的数据 可以发现seat上面的数据就是got表，s ......

28.循环语句for in
循环语句-for-in Python并没有提供类似C语言中那种传统意义上的for循环，而是提供了一种专门处理字符串，元组，列表，字典等可迭代的序列类型数据的增强型for循环。 遍历可迭代对象 使用for-in循环处理可迭代对象，可以使操作过程变的极其简单。 遍历字符串 s = "Hello Hogw ......
