begins with two single-digit numbers. The next number is obtained by adding the first two numbers
together and saving only the ones digit. This process is repeated until the “necklace” closes by returning
to the original two numbers. For example, if the starting two numbers are 1 and 8, twelve steps are
required to close the necklace: 1 8 9 7 6 3 9 2 1 3 4 7 1 8
Create a Necklace application that prompts the user for two single-digit integers and then displays the
sequence and the number of steps taken. The application output should look similar to:
I can't seem to figure it out.
Any help?
I tried doing this, but there is no output. It seems to just freeze my computer.
CODE
public class Necklace {
public static void main(String[] args) {
int originalFirstNumber = IBIO.inputInt("Enter the first starting number: ");
int originalSecondNumber = IBIO.inputInt("Enter the second starting number: ");
System.out.println(necklace(originalFirstNumber, originalSecondNumber));
}
private static String necklace(int originalFirstNumber,int originalSecondNumber)
{
String output;
int firstNumber = originalFirstNumber;
int secondNumber = originalSecondNumber;
do{
output = originalFirstNumber + " " + originalSecondNumber + " ";
int result = firstNumber + secondNumber;
String resultInString = " " + result;
int lastNumberOfResult = resultInString.charAt(resultInString.length() - 1);
firstNumber = secondNumber;
secondNumber = lastNumberOfResult;
output += secondNumber + " ";
}
while(!(firstNumber == originalFirstNumber) && !(secondNumber == originalSecondNumber));
return output;
}
}
public static void main(String[] args) {
int originalFirstNumber = IBIO.inputInt("Enter the first starting number: ");
int originalSecondNumber = IBIO.inputInt("Enter the second starting number: ");
System.out.println(necklace(originalFirstNumber, originalSecondNumber));
}
private static String necklace(int originalFirstNumber,int originalSecondNumber)
{
String output;
int firstNumber = originalFirstNumber;
int secondNumber = originalSecondNumber;
do{
output = originalFirstNumber + " " + originalSecondNumber + " ";
int result = firstNumber + secondNumber;
String resultInString = " " + result;
int lastNumberOfResult = resultInString.charAt(resultInString.length() - 1);
firstNumber = secondNumber;
secondNumber = lastNumberOfResult;
output += secondNumber + " ";
}
while(!(firstNumber == originalFirstNumber) && !(secondNumber == originalSecondNumber));
return output;
}
}
Thanks.
