solution: the charAt function starts with 0, so the 8th character in the string would be d. str.length will return 18, and the substring from index 0 to 5 is “donut”

Solution is now up for this week's homework: https://replit.com/@offexe/10-6hw#Main.java Note that you do not have to create a new function for calculating the average. The important part is making sure you used a double instead of an int.

Hello everyone, The solution for last week's homework can be found here: https://replit.com/@offexe/9-8hw For future reference all homework solutions (that are applicable) will be located on my repl.it account. Again, since everyone has a different name, your code will look different, but the idea is still the same. See y'all tomorrow!

1. (This code is probably wrong and apparently it also has a few errors that I'm not sure how to fix. Also, there's a lot of "System.out.println"s that I added for testing purposes) import java.util.Scanner; class Main { public static void main(String[] args) { Scanner scanGoBrr = new Scanner(System.in); System.out.println("Enter input:"); String input = scanGoBrr.nextLine(); scanGoBrr.close(); System.out.println("Your input is: "+ input); String[] splitted = input.split(", "); String[] cards = new String[splitted.length+2]; for(int i = 0; i < splitted.length; i+=2) { cards[i] = splitted[i].concat(splitted[i+1]); System.out.println(cards[i]); } String[] playerCard = cards[0].split(""); System.out.println("The suit of the player's card is " + playerCard[1]); System.out.println("The card's number is " + playerCard[0]); String[] validCards = new String[]{"aa", "aa", "aa"}; int x = 0; for(int i = 1; i <= cards.length-1; i++) { if(cards[i].contains(playerCard[1]) == true) { validCards[x] = cards[i]; x++; System.out.println(validCards[x]); } } boolean foundCard = false; while(foundCard == false) { if(validCards[i].contains(Integer(i).toString()) == true) { foundCard = true; System.out.println(validCards[i]); } else { while(foundCard == false) { if(validCards[i].contains(Integer(i).toString()) == true)) { foundCard = true; System.out.println(validCards[i]); } } } } if(foundCard == false) { System.out.println("NONE"); } } } 2. f(6,3) = 22 - William
