Arrya Code

in question read following: if you're doing comparatively few operations, ie less 1000 or enqueue/dequeues in total, array faster because contiguous in memory. my question is: how caching arraylist works in java? there cases, when arraylist implemented queue or stack perform better linkedlist implemented in java? hen arraylist implemented queue or stack perform better linkedlist implemented in java? when queue empty or 1 element, arraylist faster , creates less garbage (ie none) if have fast consumer, consumer ever producer produces produces it. means there typically 0 or 1 elements in queue. under these conditions arraylist faster doesn't create objects or produce garbage. btw arraydeque better choice because performs if there more 1 element. how caching arraylist works in java? there nothing special way cpu caches accesses arraylist.

#include <stdatomic.h> void request_number(request_t *request) { static atomic_int counter; request->id = atomic_fetch_add_explicit(&counter, 1, memory_order_relaxed); printf("request assigned id %u\n" request->id); } in above c snippet, believe it's ok use memory_order_relaxed , because without memory fences compiler not re-arrange call printf , fetch of request->id , before store of value request->id . is correct? i'm wanted absolutely sure in case there other things need taken account atomics. you doing 1 atomic operation , when return have value. else done "normal" memory model sequential code, has been. the ; @ end of assignment sequence point. approach fine. indeed, thing need atomic operation here is undivided, don't need sequencing guarantees of "normal" atomic operations.

given these 2 sum types: data foo = int | b string data bar = c int | d string i'd define function returns either (foo or bar) string . so, attempted make: data higher = foo | bar but failed compile: *adt> :r type checking ./adt.idr adt.idr:3:6:main.foo defined adt.idr:4:6:main.bar defined how can create higher data type, consists of foo or bar ? yes can indeed! data foo = int | b string data bar = c int | d string data higher : type injfoo : foo -> higher injbar : bar -> higher now can injfoo (b "hello") or injbar (c 5) .

ifstream fin; ofstream fout; char ch; string st; fin.open("testfile.txt"); fout.open("testfile.txt"); while(!fin.eof()) { fin.get(ch); cout << ch; } fin.clear(); fin.seekg(ios::beg); while(!fin.eof()) { getline(fin, st); cout << st; } test file contains following: abcd efg 1234 hij result: abcd efg 1234 hijabcd efg1234 hij what asking is: why results different between reading fin.get(ch) , getline(fin, st)? get() returns every character. getline() throws away line terminator.

using excel 2010, how calculate min or max column a, when needs take value of column b consideration? so table looks this amt spent quintile 545,40 q1 2146,41 q1 753,66 q2 821,11 q2 2157,99 q3 718,06 q3 526,58 q4 1047,50 q4 2009,30 q5 824,99 q5 to maximum quintile "q1" : =aggregate(14, 6, a:a*(b:b="q1"), 1) to minimum quintile "q1" : =aggregate(15, 6, a:a/(b:b="q1"), 1) you can place cell reference in place of hard-coded constant "q1" . i.e. =aggregate(14, 6, a:a *(b:b=b2), 1)

i purchased heart rate fitbit charge hr , want implement app information heart rate. tried read sensor through example uses bluetooth low energy (link: https://developer.android.com/guide/topics/connectivity/bluetooth-le.html ). able connect devices not information measure heart rate. have refer https://dev.fitbit.com api same , generate consumer key , consumer secret. seems web application only. want fitbit android bluetooth api data fitbit android apps on bluetooth. please me. the charge hr has no support rebroadcasting hr on standard btle profile want able collect data way live. chance if have private api surprised if have live data. recorded data yes live data no. 'can re-broadcast heart rate data' line interested in in dc rainmaker product comparison chart. http://www.dcrainmaker.com/2015/02/fitbit-charge-review.html the live rebroadcast feature rare there devices it, more ant+ though btle.
