# std::experimental::basic_string_view::find_last_of

From cppreference.com
< cpp‎ | experimental‎ | basic string view

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

Finds the last character equal to any of the characters in the given character sequence.

1) Finds the last occurence 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).

### [edit] 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

### [edit] Return value

Position of the last occurrence of any character of the substring, or npos if no such character is found.

### [edit] Exceptions

1-2)
`noexcept` specification:
noexcept

### [edit] Complexity

O(`size()` * `v.size()`) at worst.
