title: Check if array Is235
body: <p>I want to check if an array Is235. Is235 is an array that has an integer divisible by 2, another integer divisible by 3 and a third integer divisible by 5. The other integers in the array that aren’t divisible by either of 2, 3, or 5 when added to the integers divisible by 2, 3 and 5 should be equal to the total number of elements in the array. Return 1 if the array Is235, else return 0. Please note that array cannot contain negative integers or zero. I want to approach this in a brute force manner only, thanks for your help in advance.
  My wrong attempt -  </p>
  
  <pre><code>public class Array {
  
      public static void main(String[] args) {
  
          int[] arr = {2, 3, 5, 7, 11};
  
          System.out.println(is235Array(arr));
      }
  
      public static int is235Array(int[] a) {
          int n = a.length;
          int countOne = 0;
          int countTwo = 0;
  
          for (int i = 0; i &lt; a.length; i++) {
              if (a[i] / 2 == 0 || a[i] / 3 == 0 || a[i] / 5 == 0) {
                  countOne++;
              }
          }
          for (int j = 0; j &lt; a.length; j++) {
              if (a[j] / 2 != 0 || a[j] / 3 != 0 || a[j] / 5 != 0) {
                  countTwo++;
              }
          }
          if (countOne + countTwo != n) {
              return 0;
          }
          return 1;
      }
  }

  <p>My countOne and countTwo variables couldn't count the integers as i taught it would.</p>
