i'm newbie
with a stupid problem

a function for find repetead sublist in faster way

f[{1,2,1,2,1,2},{1,2}]-> True cause {1,2} is repated three times
f[{1,2,3,1,2,3},{1,2,3}]-> True cause {1,2,3} is repeated two times
f[{1,2,1,2,3},{1,2}]->False cause after two {1,2} there is another

True if the second list in containes many times exactly in first list
False otherwise.

bye everyone and sorry for my stupidity.
