Eh? I'm not sure you understand the problem correctly.
The problem is just asking whether successive elements vary more than a
certain amount, where the maximum variance is one less than the number
of elements in the sequence. "4 1 2 3" matches because no successive
elements vary by more than 3, where 3 is the number of elements minus
one. "8 6 2" does not match because the difference between 6 and 2 is
too large.
