std::basic_string_view::find_last_not_of
constexpr size_type find_last_not_of(basic_string_view v, size_type pos = npos) const; | (1) | (since C++17) |
|---|---|---|
constexpr size_type find_last_not_of(CharT c, size_type pos = npos) const; | (2) | (since C++17) |
constexpr size_type find_last_not_of(const CharT* s, size_type pos, size_type count) const; | (3) | (since C++17) |
constexpr size_type find_last_not_of(const CharT* s, size_type pos = npos) const; | (4) | (since C++17) |
查找最后一个字符，该字符不等于给定字符序列中的任何字符。
1%29发现最后一个字符不等于v在这个视图中，从位置开始pos...
2%29相当于find_last_not_of(basic_string_view(&c, 1), pos)...
3%29相当于find_last_not_of(basic_string_view(s, count), pos)...
4%29相当于find_last_not_of(basic_string_view(s), pos)...
参数
v | - | view to search for |
|---|---|---|
pos | - | position at which to start the search |
count | - | length of the string of characters to compare |
s | - | pointer to a string of characters to compare |
ch | - | character to compare |
返回值
最后一个字符的位置不等于给定字符串中的任何字符，或npos如果找不到这样的角色。
例外
1-2%29

复杂性
O%28size()%2Av.size()%29最坏。
