Palindrome Numbers

Question

Sorry if my Engslish is too bad, but in this project I can pass test case 1,2,5,6; but I can't pass test case 3,4, someone can explain to help me where I'm wrong
#include <iostream>
#include <cmath>
#include <vector>
using namespace std;
vector<int> assign_arr(int n, int max)
{
vector<int> arr;
while ((n / max) != 0 && max != 1)
{
arr.push_back(n/max);
n = n % max;
max = max / 10;
}
arr.push_back(n);
return arr;
}
bool isPalindrome(vector<int> arr)
{
//complete the function
vector<int> arr_1 = arr;
int x = arr_1.size();
cout << x << endl;
if (arr_1.size() % 2 != 0)
{
for (int i = 0; i < arr_1.size(); i++)
{
if (arr_1[i] == arr_1[x] && i != x)
{
return true;
}
x = x - 1;
}
}
else if (arr_1.size() % 2 == 0)
{
for (int i= 0; i < arr_1.size(); i++)
{
if(arr_1[i] == arr_1[x] && i < x)
{
return true;
}
x = x - 1;
}
}
else if (arr_1.size() == 1)
{
return true;
}
return 0;
}
int main() {
int n;
cin >>n;
cout << endl;
int max = pow(10, 9);
while (n/max == 0) //check the number of elements in the number
{
max = max / 10;
}
vector <int> arr = assign_arr(n,max);
if(isPalindrome(arr))
{
cout <<n<<" is a palindrome";
}
else {
cout << n<<" is NOT a palindrome";
}
return 0;
}

You should tell about those cases u cant satisfy
