i have intervals of form (a1, b1), (a2, b2), ...., (an, bn) . support following operations adding new interval. deleting existing interval. given point, find intervals not overlap point. intervals tree straightforward solution if want find intervals overlap point. case when want find non intersecting intervals? have nodes in 2 trees simultaneously. tree holds them key ai , tree b holds them key bi . insertion , deletion o(log n) . requirement 3, print nodes in b smallest biggest , stop when bi still smaller point. same, backwards, in a. example: given (1,10), (5,18), (13,20) , , point 12 . interval(s) in ai bigger 12 (13,20) , , in b interval(s) smaller (1,10) .

how match exact word contains special character ? $string = 'fall in love #pepsimoji! celebrate #worldemojiday downloading our keyboard @ http://bit.ly/pepsikb & take text game notch. - teacher'; preg_match("/\b#worldemojiday\b/i",$string); //false i want match exact word containing character. if want match word 'download' in string, should return false preg_match("/\bdownload\b/i",$string); //false but when search downloading, should return true. thanks the problem \b word boundary before # non-word character. \b cannot match position between 2 non-word (or between 2 word) characters, thus, not match. a solution either remove first \b , or use \b (a non-word boundary matching between 2 word or 2 non-word characters) instead of it. \b#worldemojiday\b or #worldemojiday\b see demo (or this one ) note \b matches @ beginning of string. here a way build regex dynamically, adding word boundaries necessary: ...
