Implement countSubstrings() Function to count number of substring occurrences in the string: - in case of needle is multi char - counts non-intersecting substrings - the code is based on position helpers. The following new functions is available: - countSubstrings() - countSubstringsCaseInsensitive() - countSubstringsCaseInsensitiveUTF8() v0: substringCount() v2: - add substringCountCaseInsensitiveUTF8 - improve tests - fix coding style issues - fix multichar needle v3: rename to countSubstrings (by analogy with countEqual()) 2020-11-26 18:16:07 +00:00
