I want to check for palindrome within an array. But this function isn't working. Please correct THIS function. Provide detailed explanation.

#include  #include  using namespace std; bool checkPal(int arr[], int size) { if (size == 0) return true; if (arr[0] == arr[size-1]) { return checkPal(arr + 1, size - 1); } else { return false; } } int main() { int arr[6] = { 1,3,2,2,3,1 }; cout << checkPal(arr, 6); //Output true if it is palindrome }
