Parameters v - view to search for pos - position at which to start the search count - length of the string of characters to search for s - pointer to a string of characters to search for ch - character to search for Return value Position of the first occurrence of any character of the substring, or npos if no such character is found. Complexity O(size() * v.size()) at worst.
