I rewrote the parenthesis-insertion code to present the essence of the algorithm with less distracting C-machination (eliminated a couple of tables & some peculiar end-cases, open-coded a loop) -- and to make lines shorter, and to make gcc -Wall compile it without complaint. I'll note here that it doesn't do anything about getting operator associativity right. In particular, using the usual rules, a^b^c should come out to a^(b^c) while a-b-c should be (a-b)-c. The present program adequately parenthesizes neither. Tom Duff 19:20, 23 August 2006 (UTC)[reply]

While I'm here, it would be a good idea for some motivated person to rewrite the pseudo-code for the railway-siding algorithm in C or something. Tom Duff 19:28, 23 August 2006 (UTC)[reply]
