Re: Question about using telescoping with recurrence in studying algorithms.

The use of telescoping in order to come up with a solution is
not intuitive to me. Could someone please point to a website or
book that will very explicitly go through each step and explain
this process in detail? Often in Sedgewick's Algorithms in C++
book when it says with x, y, z it is clear that a, b,c... it is
not clear to me.

I think you are referring to repeatedly substituting the right-hand
side of a recurrence relation into itself in order to guess the form
of its solution -- what Alf dug up is about something else entirely.
I can't point you anywhere in particular, but you might start by
looking over the hits on
for something with the level of detail you seek.
