Java > Array-2 > lucky13 (CodingBat Solution)

Problem:

Given an array of ints, return true if the array contains no 1's and no 3's.

lucky13({0, 2, 4}) → true
lucky13({1, 2, 3}) → false
lucky13({1, 2, 4}) → false

Solution:

public boolean lucky13(int[] nums) {
  boolean no13 = true;
  
  for (int i = 0; i < nums.length; i++) {
    if (nums[i] == 1 || nums[i] == 3)
      no13 = false;
  }
  return no13;
}
