Question

Hey, I'm working on ps3c... when I use the prof's function the program is getting caught up on my string search functions. Looks like they are stuck in an infinite loop, but they don't do this when run separately from the prof's function. I'd appreciate any insight from anyone... thanks!!

(Also, both have this problem, but I tried iterative and recursive versions of the string searching functions. Here are (1): the searching functions I've written and (2): my ps3c code with the iterative search function implemented.)

Answer 1

length = len(firstMatch)
in constrainedMatchPair function seem to be a mistake
length should be just length from the input

Answer 2

Ah, yeah I caught that earlier too, although you don't need to assign it to a variable in the definition - you can just use 'length' in the equation. That wasn't why it was caught in an infinite loop though - that problem was caused because my subStringMatchExact function couldn't handle empty strings, so I put in a condition for that. Take a look / thank so much for answering / I'll repay the favor :)
