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