Consider the values of the individual letters in Numbered Letters in their original order.

What are the English words that have a total letter value of exactly 100 when you add up all of the letters, whenever:

(I) Each of the letters in the odd positions have the same values as in the original system, but the letters in the even positions are assigned the values in reverse order (a=1, b=26, c=3, d=24, e=5, f=22, ..., y=25, z=2)?

(II) Each of the the letters in the even positions have the same values as in the original system, but the letters in the odd positions are assigned the values in reverse order(a=25, b=2, c=23, d=4, e=21, f=6, ..., y=1, z=26)?
