Hi all,

Given a list [a,b,c,d,e,f,g], I am trying to find the maxlist for overlapping subsets of 3 [{abc},{bcd},{cde},{def},{efg}].  To make things more difficult, this list needs to always retain the first and last member of the list [{a},{abc},{bcd},{cde},{def},{efg},{g}].  And, finally, I only want to know if the middle variable of each subset is equal to or greater than the other variables in the subset.

So, for the list [60,67,65,64,69,69,62], which would then be broken into the subsets [{60},{60,67,65},{67,65,64},{65,64,69},{64,69,69},{69,69,62},{62}] I want to return the value: [60, 67, 69, 69, 62].

Any thoughts on the code I could use?
