字节跳动第3题IP还原

//我第三题的思路就是穷举，看每次分段满足IP地址的限定。

//穷举的过程是通过取余来判定满足与否的。

//下面这个代码错误出在哪里，还请大佬明示？？？

#include<iostream>
#include<stdlib.h>
using namespace std;
int main()
{
    long long IP_BUG;
    cin >> IP_BUG;
    long long temp = IP_BUG;
    int weishu = 0;
    while (temp)
    {
        temp /= 10;
        weishu++;
    }


    int result = 0;

    long long temp2 = IP_BUG;
    int max = 256;

    for (int i = 1; i < weishu; i++)
    {
        for (int j = i+1; j < weishu; j++)
        {
            for (int k = j+1; k < weishu; k++)
            {
                temp2 = IP_BUG;
                if (temp2 % (10 ^ i) < max)
                {
                    temp2 /= (10 ^ i);
                    if (temp2 % (10 ^ (j-i)) < max)
                    {
                        temp2 /= (10 ^ (j - i));
                        if (temp2 % (10 ^ (k - j)) < max)
                        {
                            temp2 /= (10 ^ (k - j));
                            if (temp2 < max)
                            {
                                result++;
                            }
                        }
                            
                    }

                }
            }
        }
    }




    
    cout << result<<endl;
    system("pause");
}
