Check if all digits of the given integer are even.

Example

• For n = 248622, the output should be**solution(n) = true**;
• For n = 642386, the output should be**solution(n) = false**.

Input/Output

• [execution time limit] 3 seconds (java)

• [memory limit] 1 GB

• [input] integer n

  Guaranteed constraints:

  1 ≤ n ≤ 109.

• [output] boolean

  true if all digits of n are even, false otherwise.

boolean solution(int n) {
    String str = Integer.toString(n);
    String [] arr = str.split("");
    
    for (String s : arr) {
        int i = Integer.parseInt(s);
        
        if (i % 2 > 0) return false;
    }
    
    return true;
}
