背诵:LeetCode 第一首 -- TwoSum 两数之和 In a realm of indices and keys, A dictionary stands, its purpose is to please. Each key, a number from 'nums', is so bright, Its value, is its index, a beacon of light. As each index explores, with a number in hand, With a tar...
runtime error: left shift of negative value -2147483648,对INT_MIN左移位。 就是LeetCode 自己的编译器比较 strict,不能对负数进行左移,就是说最高位符号位必须要为0,才能左移(此处应有尼克杨问号脸?!),好吧,你赢了。那么在a和b相 '与' 之后,再'与'上一个最高位为0,其余位都为1的数 0x7fffffff...
