public boolean sameFirstLast2(int[] nums)

Given a bunch of arrays, all with DIFFERENT lengths,
return true if the value of the 1st and last elements are the same.

public boolean sameFirstLast2(int[] nums) {
  boolean same = false;
  int len = nums.length;
  if (nums[0] == nums[len-1]) {
   same = true;
  }
  return same;
