problem !!!
i want to solve this problem
A Pythagorean triplet is a set of three natural numbers, a b c, for which,
a2 + b2 = c2
For example, 32 + 42 = 9 + 16 = 25 = 52.
There exists exactly one Pythagorean triplet for which a + b + c = 1000.
Find the product abc.
my code
public class Euler {
public static void main(String[] args) {
int i = 0;
int j = 1;
int k = 2;
while (Math.pow(i, 2) + Math.pow(j, 2) != Math.pow(k, 2) && i * j * k != 1000) {
i = j;
j = k;
++k;
}
System.out.println(i*j*k);
}
}
the out always 60 although && i * j * k == 1000 in while loop:eek:
i need helpLast edited by jperson; 01292010 at 11:04 PM.

The question isn't very clear. You say at the start you want pythagorean triples whose sum is 1000. But then in the code you check the product of the triples.
Since the first time the while loop condition is checked i*j*k=0*1*2=0, the loop condition is false and the loop body will never execute. Consequently what is output at the end of main() is zero not 60 as you state.
