Problem statement: Three digit sum - Find all the numbers between 1 and 999 where the sum of the 1st digit and the 2nd digit is equal to the 3rd digit.
Examples:
123 : 1+2 = 3
246 : 2+4 = 6
Java:
public class AssignmentFive {
public static void main(String[] args) {
int i=1;
int valuetwo;
int n=1;
int sum = 0;
int valuethree;
int valueone = 0;
String Numbers = "";
for (i = 1; i <= 999; i++) {
n = i;
while (n > 1) {
valueone = n % 10;/*To get the ones place digit*/
n = n / 10;
valuetwo = n % 10;/*To get the tens place digit*/
n = n / 10;
valuethree = n;/*To get the hundreds place digit*/
sum = valuethree + valuetwo;/*adding the hundreds place and
tens place*/
}
/*Checking if the ones place digit is equal to the sum and then print
the values in a string format*/
if (sum == valueone) {
Numbers = Numbers + n + " ";
System.out.println(Numbers);
}
}
}
}
I got my result :
1
10
100
1000
10000
100000
1000000
10000000
100000000
1000000000
10000000001
100000000011
1000000000111
10000000001111
100000000011111
1000000000111111
10000000001111111
100000000011111111
1000000000111111111
Process finished with exit code 0
The result is not showing the actual result like it should be which should show values like: 123, 246 (Please refer to the problem statement above.)
Please let me know what seems to be the issue with the code and how to tweak it.
Andreas :
Don't know what you're trying to do with that while loop, or why you are building up a space-separated string of numbers.
Your code should be something like:
for (int n = 1; n <= 999; n++) {
int digit1 = // for you to write code here
int digit2 = // for you to write code here
int digit3 = // for you to write code here
if (digit1 + digit2 == digit3) {
// print n here
}
}
