//) Design the logic to remove the duplicate elements from an Array and after the deletion the array should containtheunique elements.

using namespace std;

int main() {
    int n;

    cout << "Enter " << n << " elements: ";
    for (int i = 0; i < n; i++)

    for (int i = 0; i < n; i++) {
        for (int j = i + 1; j < n; j++) {
            if (arr[i] == arr[j]) {
                // shift elements left
                for (int k = j; k < n - 1; k++)
                    arr[k] = arr[k + 1];
                n--;   // reduce size
                j--;   // check the new element at same position
            }
        }
