i implementing data struct hash table collisions resolved using chains. so underlying data structure need vector of lists . choice 2 variants: std::vector<std::list<entry> > std::vector<std::list<entry>* > where entry struct contains data , hash value; question: huge decrease in efficiency if use first variant(question considered on large input data)? thank in advance! there's no advantage using pointer, , adds complication of needing deleted when destroy vector. go ahead , use vector<list<entry> > . list allocating memory elements anyway, invisible you. there might performance penalty if vector has resized, c++11 compiler should use moves instead of copies minimize it. , learning project performance shouldn't first concern anyway.

i have select box triggers onchange event (not code, plugin's code). select box hide/show next box according item selected. way plugin hides or shows next box changing style of element. for instance: if select option 1. plugin triggers onchange event , changes next box's style from display:none to display:list-item once item style changes, need select item , other stuff own code. problem onchange triggering before plugin's code, can't find item select. my code: ("#input").change(function(){ var mymatch = $("li[style='display: list-item;']");}); if reselect again option 1, work, because plugins function has executed once. i tried adding settimeout function, did not work. guess function needs either listen style changes, or somehow execute after plugin function... ideas? approaching wrong? you can try going more concise selector instead of style attribute, if you're looking visible list items can use $(...
