int main() {

        3,
        10,
        12,

    int newPosition = 5; // Index where you want to insert the new element
    int newElement = 7; // Element to be inserted

    // Shift elements to make space for the new element
    for (int i = n; i > index; i--) {
        arr[i] = arr[i - 1];
    }



    // Insert the new element at the specified position
    arr[index] = newElement;

    // Update the size of the array
    n++;
    // Print the updated array
    for (int i = 0; i < n; i++) {
        printf("%d", arr[i]);
    }
