load of value 64, which is not a valid value for type ‘bool‘

Line 31: Char 24: runtime error: load of value 64, which is not a valid value for type 'bool' (solution.cpp) SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior prog_joined.cpp:36:24

leetcode上刷题，在VS调试没问题，但在LeetCode上报错，检查半天最后发现是没有初始化，

比如 bool flag;

看它报错的意思是，flag没初始化，默认值随机到了一个64位的值？

总之初始化一下就没问题啦

bool flag = false;
