Searching string for entries and tabling those entries
Posted: Wed Dec 30, 2009 3:51 am
I have a string that looks like "14, 1, 4, 5, 16, 17, 2, 2, 5, 1, 5, 20, 5" etc but with many more characters (and it may end up with a few thousand characters to it in the end). Each character is between 1 and 20 (inclusive) and separated by ",".
I need to search this string and count how many times each number occurs (i.e how many 1's, how many 2's ... how many 20's). I sort of got it working using a for loop and switch statement although it was rather obfuscated.
What would be the easiest way to do this?
