Array-1 > unlucky1
prev  |  next  |  chance

We'll say that a 1 immediately followed by a 3 in an array is an "unlucky" 1. Return true if the given array contains an unlucky 1 in the first 2 or last 2 positions in the array.

unlucky1([1, 3, 4, 5]) → true
unlucky1([2, 1, 3, 4, 5]) → true
unlucky1([1, 1, 1]) → false

...Save, Compile, Run

public boolean unlucky1(int[] nums) { }
