Chapter 1, Problem 3P
Explanation of Solution
Purpose of the given code:
The given code is to product the two numbers and displays the result.
Syntax error:
An error which is occurred on the source code of a program is referred as “syntax error”; because the computer programs are strictly follows the syntax rules, if the code fails to prove its language syntax format then the compiler will throws an error.
Error in the given code:
n1=keyboard.nextInt();
n2=keyboard.nextInt();
The variables “n1” and “n2” are not declared in the given statement. Hence, it throws the syntax error.
Corrected code:
//Import required package
import java.util...

Instructions
The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly.
An example of the program is shown below:
Enter name Juan Hello, Juan!
Task 1: The DebugThree3 class compiles without error.
Task 2: The getName() method accepts user input for a name and returns the name value as a String.
Task 3: The displayGreeting() method displays a personalized greeting.
Task 4: The DebugThree3 program accepts user input and displays the correct output.

Python Development Lab In Merworld there exists 2 coins of different denominations types 5-peso coins and 10- peso coins, both having two faces with image of – Elon Musk and a dog. You are assigned a task to find out the number of ways to arrange these coins so that their sum is N pesos. Arrangement should be done in such a way that the first coin in the arrangement should always have Elon Musk image up. Other coins could have any image. Input Output 1 60 5 LO
- Do not add any imports, the ones that you need will be given to you.- Do not use recursion.- Do not use break/continue.- Do not use try-except statements, you should be able to anticipateor prevent any errors from happening at all!

After the user finally gets all of them correct (yes - all four), they are congratulated and then told how many tries it took them.
