Finds the first character not equal to any of the characters in the given character sequence.

1) Finds the first character not equal to any of the characters of v in this view, starting at position pos.

2) Equivalent to find_first_not_of(basic_string_view(&c, 1), pos).

3) Equivalent to find_first_not_of(basic_string_view(s, count), pos).

4) Equivalent to find_first_not_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 compare
s	-	pointer to a string of characters to compare
ch	-	character to compare

Return value

Position of the first character not equal to any of the characters in the given string, or npos if no such character is found.

Complexity

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