Hello,
I'm working on a problem in which I have to substitute a list,
for instance {a,b,c,d} by the other list {{a,b},{b,c},{c,d}}.
I've managed to solve it for a given length of the first list, by
using the substitution-rule :
{a_,b_,c_} -> {{a,b},{b,c}} (this for a list of three elements)
I would like to find out how this can be done for a list of arbitrary
length.
Yours,
