                    let userSequenceNumber = prompt("Enter The Sequence Number");
                    function fibonacci(n) {
                        if (n <= 1) {
                            return n;
                        }
                        return fibonacci(n - 1) + fibonacci(n - 2);
                    }
                    console.log(fibonacci(userSequenceNumber));
