algorithm - Given a file, find the ten most frequently occurring words as efficiently as possible -

-

this apparently interview question (found in collection of interview questions), if it's not it's pretty cool.

we told efficiently on complexity measures. thought of creating hashmap maps words frequency. o(n) in time , space complexity, since there may lots of words cannot assume can store in memory.

i must add nothing in question says words cannot stored in memory, if case? if that's not case, question not seem challenging.

optimizing own time:

sort file | uniq -c | sort -nr | head -10

possibly followed awk '{print $2}' eliminate counts.

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
