Reversing an integer can be done similarly to reversing a string. We want to repeatedly "pop" the last digit off of x and push it to the back of the rev so that in the end rev is the reverse of x.To push and pop digits without the help of some auxiliar stack/array we can use ...

代码语言:javascript 代码运行次数:0 运行 AI代码解释 INT_MAX和INT_MIN为C++内宏定义,分别表示int的最大值和最小值。 定义ret为反转后的数,初始化为0x%10取到最后一位上的数 x/10去掉最后一位上的数 相关解释: 开始的ret为0x%10将原来x的最后一位取出来,放到ret中,这个数就是ret最终结果的第一位。
