Problem:
Given an int array length 2, return true if it does not contain a 2 or 3.
no23({4, 5}) → true
no23({4, 2}) → false
no23({3, 5}) → false
Solution:
public boolean no23(int[] nums) {
return (nums[0] != 2 && nums[1] != 3
&& nums[1] != 2 && nums[0] != 3);
}
public boolean no23(int[] nums) {

if(nums[i]==2 || nums[i]==3) return false;
}
return true;
}
if (nums[0]==2 || nums[1]==2 || nums[0]==3 || nums[1]==3 ){

}
return true;
