void reverse(int arr[], int i, int j){
   if(i<j){
      int t = arr[i];
      arr[i] = arr[j];
      arr[j] = t;
      reverse(arr,i+1,j-1);
   }
}

int main() {
   int arr1[] = {1,2,3,4,5};
   cout<<"Origional Array: ";
   for(int i = 0;i<5;i++){
      cout<<arr1[i]<<" ";
   }
   cout<<endl;
   reverse(arr1, 0, 4);
   
   cout<<"Result Array: ";
   for(int i = 0;i<5;i++){
      cout<<arr1[i]<<" ";
   }
   cout<<endl;
