suppose i'm receiving 2 streams of integers. each stream of integers (1) not guaranteed in increasing order, , (2) occasionally, 1 or more integers missing first stream present on second stream. example: stream 1 - 1, 2, 3, 5, 4, 6, 8, 9, 10, ... stream 2 - 1, 2, 3, 4, 5, 6, 8, 7, 10, ... what data structures and/or algorithms low space-time complexity constructing sorted stream contains every single integer in union (i.e. duplicates removed) set of both streams? is: sorted stream - 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ... of course, naive approach store every result sort in o(n log n), making final pass in linear scan remove consecutive duplicate elements. requires lot of memory , requires both streams terminate before processing can start. this udp packet sequencer on embedded device, code snippets in c preferable, can read python too. do know integers we're getting, or arbitrary? you're going need sort @ point, don't see way avoid o(n lg n). bes...
