Hi, I want to have a regular expression that can seek all possible version of my string. (including overlapping part of my sequences) My string is dynamic, user can define it. I have a list of strings to try my input string. for example: user defined strings could be AAA AAC ACA CAA etc my strings that I want to search these are AAAAA AAACACA CAACAAA return should be AAA count: 5 AAC count: 2 ACA count: 3 CAA count: 2 I only need the regular expression, If you help me, I'll realy appreciate Thanks
