is there way automatically convert na values ? in weka while loading .csv files? or have use other script/program either replace them ? or blank space before loading weka. any or suggestions welcome. thanks unfortunately not believe weka has way conversion. case because weka's native format .arff files. in .arff files, missing values denoted "?". when .csv file loaded, expects missing values denoted "?". depending on method of using weka suggest: for weka gui, use " find , replace" in simple text editor change "na" "?" before loading .csv weka. for weka java api, write method preprocess ".csv" file before handing on weka .csv loader.

i have problem on homework reverse words in c++ string, in place, o(1) additional memory. i'm confused means o(1) additional memory. understand o(1) means, no matter how big input is, time compute constant i'm guessing should add 1 piece of memory keep track of words in reverse. suggestions? o(1) additional memory means "using @ constant additional memory." example, couldn't store copy of string, since take o(n) space, store constant number of int s, char s, etc. more generally- statements "o(1)" or "o(n)" don't refer runtimes. big-o notation way of describing functions. algorithm can't o(n), runtime can o(n). algorithm's space usage can o(1), o(n), o(2 n ), etc. hope helps!

how can add warnings in boost spirit parser. edit: ... report issue position for example if have integer parser: ('0' >> oct) | int_ i able this: ('0' >> oct) | "-0" --> trigger warning("negative octal values not supported, interpreted negative decimal value , leading 0 ignored") | int_ q. can create own callback? how? a. sure. way you'd in c++ (or @ boost signal2 and/or boost log) parser(std::function<bool(std::string const& s)> callback) : parser::base_type(start), callback(callback) { using namespace qi; start %= as_string[+graph] [ _pass = phx::bind(callback, _1) ] % +space ; boost_spirit_debug_nodes((start)); } as can see, can make handler decide whether warning should ignored or cause match fail. update #1 i've extended sample show of unrelated challenges mentioned in comments (position, duplicate checking). h
