X Y X Y Z

trying to solve in N
if we highlight all y and do it backward it might remove a z
but not an x between -xz
and wont remove x'z'yz

x yyyyyy xz yyyy z
we have to choose one

so the 2nd x will becomne uselss and the 2nd group of y
what if we remove all useless one first
then we will be left with
xyyyz xyyz xyyz
now can we just do from left to right

highlight first x and a pair of y->z 
then we can get rid of useless one then remove left to right and save the first x for last
case:
x y x y z
x y z y z

**
we can split each z then for each block do right to left but we do block left to right
we will also highlight 1 x
for case like x z y z
then we just need to remove everything so the left of the comp is x
will this work??
