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...
