//----------------------------------------------------------------Solution of Problem:----------------------------------------------------------

// 1. Converting Decimal Numbers to Octal Numbers:
function convertDecimalToOctal(decimal_number) {
let octal_number = [];

let decimal_number = 25;
let octal_number = [];
while (decimal_number > 0) {
octal_number.push(decimal_number % 8);
decimal_number = Math.floor(decimal_number / 8);
}

while (decimal_number > 0) {
octal_number.push(decimal_number % 8);
decimal_number = Math.floor(decimal_number / 8);
return octal_number.reverse().join('');
}

process.stdout.write("Octal number: ");

for (let i = octal_number.length - 1; i >= 0; i--) {
process.stdout.write(octal_number[i].toString());
}
const decimalNumber = 25;
const octalNumber = convertDecimalToOctal(decimalNumber);
console.log(`Octal number: ${octalNumber}`);

//----------------------------------------------------------------------------------------------------------------------------------------------

// 2. Reversing an Integer:
function reverseInteger(number) {
let reversed_number = 0;

let number = 12345;
let reversed_number = 0;
while (number !== 0) {
reversed_number = reversed_number * 10 + number % 10;
number = Math.floor(number / 10);
}

while (number !== 0) {
reversed_number = reversed_number * 10 + number % 10;
number = Math.floor(number / 10);
return reversed_number;
}

console.log(reversed_number);
const numberToReverse = 12345;
const reversedNumber = reverseInteger(numberToReverse);
console.log(`Reversed number: ${reversedNumber}`);

//----------------------------------------------------------------------------------------------------------------------------------------------

// 3. Printing the Fibonacci Series using Recursion:

function fibonacci(n) {
if (n <= 1) {
return n;
} else {
return fibonacci(n - 1) + fibonacci(n - 2);
}
return fibonacci(n - 1) + fibonacci(n - 2);
}

let n = 10;
process.stdout.write("Fibonacci series: ");

for (let i = 0; i < n; i++) {
process.stdout.write(fibonacci(i) + " ");
function printFibonacciSeries(length) {
let series = [];
for (let i = 0; i < length; i++) {
series.push(fibonacci(i));
}
return series.join(' ');
}

const fibonacciLength = 10;
const fibonacciSeries = printFibonacciSeries(fibonacciLength);
console.log(`Fibonacci series: ${fibonacciSeries}`);

//----------------------------------------------------------------------------------------------------------------------------------------------

// 4. Returning the Nth Value from the Fibonacci Sequence:

function fibonacci(n) {
if (n <= 1) {
return n;
} else {
return fibonacci(n - 1) + fibonacci(n - 2);
}
return fibonacci(n - 1) + fibonacci(n - 2);
}

let n = 10;
let fibonacci_number = fibonacci(n);
console.log(fibonacci_number);
const nthFibonacci = 10;
const nthFibonacciNumber = fibonacci(nthFibonacci);
console.log(`The ${nthFibonacci}th Fibonacci number is: ${nthFibonacciNumber}`);

//----------------------------------------------------------------------------------------------------------------------------------------------

// 5. Finding the Average of Numbers:
function calculateAverage(numbers) {
let sum = numbers.reduce((acc, curr) => acc + curr, 0);
return sum / numbers.length;
}

let numbers = [10, 20, 30, 40, 50];
let sum = numbers.reduce((acc, curr) => acc + curr, 0);
let average = sum / numbers.length;
console.log("Average: " + average);
const numbersArray = [10, 20, 30, 40, 50];
const average = calculateAverage(numbersArray);
console.log(`Average: ${average}`);
