Where can I get a “useful” C++ binary search algorithm? http://stackoverflow.com/questions/446296/where-can-i-get-a-useful-c-binary-search-algorithm benefits of a binary search not just any search. so far lower_bound and upper_bound fail because if the datum is missing lousy pseudo.. pseudo code vector 1 2 3 4 6 7 8 9 0 notice no 5 iter lower_bound_or_upper_bound start end 5 iter 5 iter end not returning end.. as usual instead it'll return 4 or 6 Also I really doubt lower_bound and upper_bound are implemented as binary_searches because they..
std::lower_bound slower for std::vector than std::map::find http://stackoverflow.com/questions/8784732/stdlower-bound-slower-for-stdvector-than-stdmapfind lower_bound slower for std vector than std map find I wrote a class to.. inline iterator find const key_type key iterator i std lower_bound internal_.begin internal_.end key comp_ return comp_ key i internal_.end.. most shocking of all was that the std vector using std lower_bound was slower than the std map find for all PODs. The difference..
