/** Method 1
Given an int array of any given length, return true if it does not contain a 2 or 3.
no23([4, 5, 6, 7, 8]) → true
no23([4, 2, 1, 1, 1]) → false
no23([3, 5, 3, 6, 1]) → false
Key ideas:boolean return type; array basic loop; condition check
**/
/** Method 2
Given an array of ints, return true if the array does not contain 1 and 3 both (anywhere in the array).
lucky13([0, 2, 4]) → true
lucky13([1, 2, 3]) → false
lucky13([1, 2, 4]) → true
lucky13([2, 3, 4]) → true
lucky13([3, 1, 4]) → false
lucky13([1, 3]) → false
lucky13([3,3,1]) → false
Key ideas: basic for-each loop (or for loop); iterating through loop; conditional check
**/
/** Method 3
Given 2 int arrays, return a new array length containing all the elements.
plusTwo([1, 2], [3, 4, 5]) → [1, 2, 3, 4, 5]
plusTwo([4], [2, 2, 2]) → [4, 2, 2, 2]
plusTwo([9, 2, 3, 5, 7], [3, 4, 1, 4, 5]) → [9, 2, 3, 5, 7, 3, 4, 1, 4, 5]
