Print the given statement in rust language 10 times "Programming is more fun  using loops

Python  A program to calculate the value of some change in dollars  Code evaluation (What is the result of the following code?)- Short sentence(What is the difference between X and Y?)- Translation (Convert the following code from a for loop to a while loop)

I am having an issue with this program, I keep getting the number 15 everytime I type in a code. There is also the instructions for the module itself. //PSEUDOCODE    //Write a program that prompts the user for a binary number    //(from 3 to 8 bits) as a String and converts it to base-10 decimal value    //There are several ways to do this in Java but your program must use a for loop and first principles to perform the conversion    //Print the base-10 number when the loop ends    public static void main(String args[]) {        long sum = 0;                System.out.println("Enter a binary number: ");        Scanner scan = new Scanner(System.in);        String s = scan.next();                long result = 0;        for (int i = 0; i < s.length(); i++) {            result = (long) (result + (s.charAt(1) - '0') * Math.pow(2, s.length()- i - 1));        scan.close();        }        System.out.println(result);            }}

Rewrite the following pseudocode segment using a loop structure. any language is fine, but don’t use gotos (Use Python or C++)   i= 10; num = 0; loop:    if i >= 20 then goto out    i = i + 3;    cout << i * num;    goto loop out:  cout << “DONE”;
