consider following: >>> import re >>> = "first:second" >>> re.findall("[^:]*", a) ['first', '', 'second', ''] >>> re.sub("[^:]*", r"(\g<0>)", a) '(first):(second)' re.sub() 's behavior makes more sense initially, can understand re.findall() 's behavior. after all, can match empty string between first , : consists of non-colon characters (exactly 0 of them), why isn't re.sub() behaving same way? shouldn't result of last command (first)():(second)() ? you use * allows empty matches: 'first' -> matched ':' -> not in character class but, pattern can empty due *, empty string matched -->'' 'second' -> matched '$' -> can contain empty string before, empty string matched -->'' quoting documentation re.findall() : empty ...

a large array array[n] of integers given input. 2 index values given - start,end . desired find quickly - min & max in set [start,end] (inclusive) , max in rest of array (excluding [start,end]). eg- array - 3 4 2 2 1 3 12 5 7 9 7 10 1 5 2 3 1 1 start,end - 2,7 min,max in [2,7] -- 1,12 max in rest - 10 i cannot think of better linear. not enough n of order 10^5 , number of such find operations of same order. any highly appreciated. you're asking data structure answer min , max queries intervals on array quickly. you want build 2 segment trees on input array; 1 answering interval minimum queries , 1 answering interval maximum queries. takes linear preprocessing, linear space, , allows queries take logarithmic time.

i working on mvc 2 visual studio 2010 , view engine aspx kind of project. so have decided move visual studio 2012 mvc 4 , view engine razor . so achieve above task.if how ? i hear experience similar kind of situation. note : project large one. create new mvc4 project in visual studio 2012 , add source files old solution new solution 1 @ time. moving mvc3 mvc4 easier new solution, have imagine going 2 -> 4 more complex try upgrade in-place. conversion aspx razor should done manually. although there converters out there (like this one or code accepted answer in this question ), wouldn't trust application pure automation. also, convert 1 @ time. in other words, convert aspx -> razor or mvc2 -> mvc4 first , make sure works conversion. convert other 1 if run problems, don't have try figure out whether it's version upgrade or syntax upgrade caused problem.

i read everywhere if call clone() without implementing cloneable interface clonenotsupportedexception. if implement clone method in class not implement cloneable, can still call clone() w/o exception. mean implementing cloneable makes no difference. please elaborate........ implementing cloneable interface tells programmer object should have valid clone method. if looked @ cloneable interface find comment looks this note interface not contain clone method. therefore, not possible clone object merely virtue of fact implements interface. if clone method invoked reflectively, there no guarantee succeed. the cloneable interface programming practice programmer should follow if add implementation clone.

can tell me how 2-d gaussian function given as- http://upload.wikimedia.org/math/f/7/3/f7352f2a6fea01707e869432d39bfc21.png where t standard deviation. how convoluted image(as in difference of gaussian)? what difference between gaussian function , gaussian filter? based on formula filter mask constructed in (aka discrete version of gaussian function): http://homepages.inf.ed.ac.uk/rbf/hipr2/gsmooth.htm this example gaussian filter mask: 1). this how convolution filter mask done: http://www.songho.ca/dsp/convolution/convolution2d_example.html basically filter flipped , filter moves on image. while moving on image, image pixel corresponds middle of mask gets value of weighted sum of mask , pixels. ( link explains better example) 2). gaussian function ==> continues gaussian filter ==> in case, discrete filter mask
