C++, finding 3 max values in array, where difference between these values is one of the parameter -


i have find 3 max values in array of real data. problem fact these 3 values must vary particular, minimum value (which parameter). means if have array 10 elements {1,2,3,4,5,6,7,8,9,10} 3 max values in array 8,9,10 if value of parameter example "2" these 3 max values must vary @ least "2", real max values in case 10, 8, 6. believe algorithm of program this:

1) find 3 max values (loop) 2) verify if vary @ least parameter 2a) if yes return these 3 values 2b) if not, go loop, search again 3 values ignore value doesn't fulfill condition?

i can't imagine real code in c++ solution. can give piece of advice how it?

easier sorting scan array 3 times. first time, find max. next time, find largest number <= (max - p) etc.

have studied big-o notation evaluation of algorithm performance?

compare time sort & search (n * lg(2)n + n) time search 3 times (3*n) break-even performance happens @ pretty small value of n.

python - How to insert QWidgets in the middle of a Layout? -

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
