Storing multiples of 13 in array

Salut, invat de putin timp java.Un exercitiu din ceva carte suna cam asa:
"Write a program that stores the first 400 numbers that are multiples of 13 in an array."
am facut asa:

class Multiple13{
public static void main(String[] args){
int multiple[]=new int[400];
for (int i=0;i<400;i++){
multiple[i]=13*(i+1);
System.out.print(multiple[i]+" ");
}
}
}

La solutii era rezolvat asa:

class ThirteenStorer {
public static void main(String arguments[]) {
int[] thirteens = new int[400];
int numFound = 0;
// candidate: the number that might be a multiple
// of 13
int candidate = 1;
System.out.println("First 400 multiples of 13:");
while (numFound < 400) {
if (candidate % 13 == 0) {
thirteens[numFound] = candidate;
numFound++;
}
candidate++;
}
System.out.println("First 400 multiples of 13:");
for (int i = 0; i < 400; i++) {
   System.out.print(thirteens[i]+" ");
}
}
}



Ambele variante au acelasi output.Intrebarea e daca am facut corect sau imi scapa ceva?
Ms.

E mai optim cum ai facut tu.

Nu exista o solutie universala.
A ta e chiar mai ok decat cealalta, fiindca nu stai sa tot aduni cate 1.

Multumesc pt raspunsuri si promptitudine.
