Hi guys , is me again !
I get stucked on this question
Write a program that read an integer and display its smallest prime factors in ascending order. For example, if the input is 60, the output should be 2,3,5...
I came out with below code, but I get 2 2 3 5.How to have only one 2 ?
package chapter4;
import java.util.Scanner;
public class Exercise4_16 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter an integer: ");
Exercise4_16 exe = new Exercise4_16();
int value = input.nextInt();
exe.primeFactors(value);
}
public void primeFactors(int value) {
while (value % 2 == 0) {
System.out.print(2 + " ");
value = value / 2;
}
for (int i = 3; i <= Math.sqrt(value); i = i + 2) {
while (value % i == 0) {
System.out.print(i + " ");
value /= i;
}
}
if (value >= 2) {
System.out.print(value);
}
}
}
