🎀 std::experimental::basic_string_view::find_last_of

okay bestie, this is the std::experi...ind_last_of(3) page from the C++ Standard Libary manual — manual name folded in near the top like a little name tag, because we are not copy-pasting the header line, we are giving it main character energy 💅✨

✨ NAME ✨

std::experimental::basic_string_view::find_last_of — std::experimental::basic_string_view::find_last_of

🦋 Synopsis

          constexpr size_type find_last_of(basic_string_view v,      (1)
       (library fundamentals
          size_type pos = npos) const noexcept;                          TS)
          constexpr size_type find_last_of(CharT c, size_type pos =  (2)
       (library fundamentals
          npos) const noexcept;                                          TS)
          constexpr size_type find_last_of(const CharT* s, size_type (3)
       (library fundamentals
          pos, size_type count) const;                                   TS)
          constexpr size_type find_last_of(const CharT* s, size_type (4)
       (library fundamentals
          pos = npos) const;                                             TS)

okay so the whole vibe: it finds the last character equal to any of the characters in the given character sequence. Periodt. 🫶

1. Finds the last occurrence of any of the characters of v in this view, starting at position pos.
2. Equivalent to find_last_of(basic_string_view(&c, 1), pos).
3. Equivalent to find_last_of(basic_string_view(s, count), pos).
4. Equivalent to find_last_of(basic_string_view(s), pos).

🌸 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 last occurrence of any character of the substring, or npos if no such character is found. no cap, if it’s not there, it’s npos 😭

🔥 Complexity

O(size() * v.size()) at worst. that’s the worst-case energy, bestie 💀
