I suspect all > methods which can be converted into a loop via tail recursion > optimization are as simple as factorial. I taught introductory programming for several years in several languages. You don't need to get as complex as backtracking. The natural places to teach recursion to introductory students are with binary tree search and quicksort, both of which can be taught in the first or second 1-semester course. -+- BBBS/Li6 v4.10 Dada-1 + Origin: Prism bbs (1:261/38) -+- Synchronet 3.16a-Win32 NewsLink 1.98 Time Warp of the Future BBS - telnet://time.synchro.net:24 --- BBBS/Li6 v4.10 Dada-1 * Origin: Prism bbs (1:261/38) --- Synchronet 3.16a-Win32 NewsLink 1.98 Time Warp of the Future BBS - telnet://time.synchro.net:24
