PRoblem and smaple run is attached. I have my code written but keep getting error issues and want to see what im doing wrong.

Enter the number of sides: 5
Enter the side: 6.5
The area of the polygon is 72.69017017488385

**Geometry: Area of a Regular Polygon**

A regular polygon is an $ n $-sided polygon in which all sides have the same length and all angles are equal. The polygon is both equilateral and equiangular. The formula for computing the area of a regular polygon is:

\[
\text{Area} = \frac{n \times s^2}{4 \times \tan\left(\frac{\pi}{n}\right)}
\]

**Instructions**

Write a method that returns the area of a regular polygon using the following header:

```java
public static double area(int n, double side)
```

Write a main method that prompts the user to enter the number of sides and the length of a side of a regular polygon and displays its area. Here is a sample run:

[Sample code and user interaction would be added here.]

I am writing code for javascript. The code is a histogram using stars (astericks), I need to take user input (using readline.sync) and the out put shows in rows the astericks and the columns are the numbers that where typed in going straight down, at the end after entering the zero to stop the program. It goes from 1-100 for the number that can be entered by the user if they want to quit they must enter 0. I am very confused on the looping system when it comes to arrays and my book doesn't help me very well. My array needs to start at index 0, and add 1 to the index. And I was told to use the max function. I was also told to not over complicate the histogram, the histogram display only involves printing an asterick for the number of times a number is contained in the array. This is what I have at the moment, and I'm still working on it. const readlineSync = require('readline-sync');let arr =[];let num = readlineSync.question("Enter a number between 1 and 100, or enter 0 to exit: ");…
