修改思路:
1.数组 s 初始化的循环条件修正:
原错误文件中,循环条件是 for (int i = 1; i < 105; ++i),这意味着数组 s 的第一个元素 s[0] 将不会被初始化。
修改后的文件中,循环条件是 for (int i = 0; i < 105; ++i),这样确保了数组 s 的所有元素都被正确初始化。
2.循环变量 n 的定义修正:
原错误文件中,n 被定义为 favoriteCompanies.size()-1,这会导致最后一个元素被忽略。
修改后的文件中,n 被正确定义为 favoriteCompanies.size(),确保了所有元素都被考虑。
3.循环遍历 favoriteCompanies 的顺序修正:
原错误文件中,填充 s 数组的循环和检查是否为子集的循环是嵌套的,这是逻辑错误,因为应该先填充完所有的集合,再进行子集的检查。
修改后的文件中,两个循环是顺序执行的,首先填充 s 数组,然后进行子集的检查。
4.检查是否为子集的逻辑修正:
原错误文件中,ans 集合添加索引的条件是 if (isSub),这意味着如果当前清单是其他清单的子集,它的索引会被添加到答案中,这是错误的。
修改后的文件中,ans 集合添加索引的条件是 if (!isSub),这意味着只有当当前清单不是其他任何清单的子集时,它的索引才会被添加到答案中,这是正确的逻辑。
5.check 方法的逻辑修正:
原错误文件中,check 方法的逻辑是正确的,但是因为其他部分的错误,导致整体结果不正确。
修改后的文件中,check 方法的逻辑保持不变,因为它本身是正确的。
