i trying re order cells based on priority (an enum). have double checked enum values correct. here enum enum priority{ case low case neutral case high case urgent } as can see, lower priority has lower hash values. trying compare 2 cells; cell , cell above it. if cell's value greater 1 above it, shift upwards. obtain indexpath of cell above using var newindexpath = indexpath(row: indexpath.row - 1 , section: indexpath.section) after comparing enum values using if(comparepriority.hashvalue < priorityvalue.hashvalue) i attempt switch order using tableview.moverow(at: indexpath, to: newindexpath) the result interesting, use pictures explain. note of code in cellforrowat function , cells given priority correspond name except "test", these pictures taken in slow motion meaning user wouldn't able see switch happening. mid-segue cells finish switching just sort array of items according these priorities , table reload. i

i have class city: class city(object): #a city has 2 coordinates in graph(x,y), , set of order def __init__(self, name, x, y, orders): self.name = name self.x = x self.y = y self.orders = orders i create list of cities: example: list_cities = [city1, city2, city3, city4] city1 (0.0, 0.0) [1, 2] city2 (1.0, 0.0) [2, 3] city3 (2.0, 0.0) [1, 3] city4 (3.0, 0.0) [2] i group cities orders this: list1 = [city1, city3] list2 = [city1, city2, city4] list3 = [city2, city3] i've tried dictionaries, list lists , sets still not give me results , not know how else it. leave code have tried: tours = [] city = city.create(arraycity) in range(0,len(city.orders)): tours[city.orders[i]].append(city) this outputs: indexerror: list index out of range i hope can me. thank much class city: def __init__(self,name,x,y,orders): self.name = name self.x = x self.y = y self.orders = orders ci

consider following definition binary trees: data tree = nil | node (tree a) (tree a) the foldable instance can defined follows: instance foldable tree foldr _ z nil = z foldr f z (node l d r) = foldr f (f d (foldr f z l)) r but problem elem function runs in o(n) rather o(log n) . when try implement custom elem : elem x nil = false elem x (node l d r) | x == d = true | x < d = elem x l | otherwise = elem x r i could not deduce (ord a) arising use of ‘<’ . how can problem fixed? you cannot use elem method foldable class, since foldable api requires elem implementation of instances able search elements of type eq instance. "an elem polymorphic eq " intentional choice in design of foldable typeclass. your elem function, while useful, not compatible elem method foldable typeclass, since not generic enough typeclass's desires. best way export elem function type define separate function outside of typeclass.

so have these 2 similar functions in scala, both convert jsvalue java typed number , differ specific type: import play.api.lib.json._ import java.lang.{double => javadouble, integer => javainteger} def getdouble(jsdouble : jsvalue) : javadouble = { val strdouble : string = jsdouble.asinstanceof[jsstring].value.replace(",", "") val jdouble : javadouble = javadouble.valueof(strdouble) jdouble } def getinteger(jsinteger : jsvalue) : javainteger = { val strinteger : string = jsinteger.asinstanceof[jsstring].value.replace(",", "") val jinteger : javainteger = javainteger.valueof(strinteger) jinteger } since they're similar, each other, hoping combine them 1 function , and use generic type differ 2 , pattern match type: def getnumber[t](jsnumber : jsvalue) : t = { val strnumber: string = jsnumber.asinstanceof[jsstring].value.replace(",", "") t.valueof(strnumber) match { case typeof[javaint

i don't meaning of super.run(); and super.handlemessage(msg); necessaary? where should code written? before super.run(); / super.handlemessage(msg); or after them? new thread(){ @override public void run() { super.run(); } }.start(); / handler handler = new handler() { @override public void handlemessage(message msg) { super.handlemessage(msg); } }; question i don't meaning of super.run() , super.handlemessage(msg) necessaary? where should code written? before super.run() or after them? answer - 1 this unnecessary in code in question. new thread(){ @override public void run() { super.run(); } }.start(); public class thread implements runnable { ... @override public void run() { if (target != null) { target.run(); } } ... } super.run call thread class. therefore, not necessary because there empty function. answer - 2

i know python interpreter executes command line line without compiling entire program @ start. not understood why catching syntax errors on next subsequent lines without executing starting lines. for example, in script, if write following statements: print("i first") print("second") print(third") # syntax error. missed 1 " this gives below output: file "script2.py", line 3 print(third") ^ syntaxerror: eol while scanning string literal i expecting output below: i first second file "script2.py", line 3 print(third") ^ syntaxerror: eol while scanning string literal i keen learn why python interpreter exhibits behavior. it depends on how run python interpreter. if give full source file, first parse whole file , convert bytecode before execution instruction. if feed line line, parse , execute code block block so go one line @ time

is there method check if ip addresses network range present in subnets of ip range? example: 10.0.1.0/18 in 123.1.0.0/8 if exists, need return true, else false. since python 3.3, can use ipaddress module of standard library: from ipaddress import ipv4address, ipv4network ipv4address('192.0.2.6') in ipv4network('192.0.2.0/28') # true ipv4address('10.0.1.0') in ipv4network('192.0.2.0/28') # false if mean if networks overlap, use overlaps : in [14]: ipv4network('10.0.1.0/24').overlaps(ipv4network('192.0.2.0/28')) out[14]: false note module marked provisional in python 3.3, no longer in 3.6. enjoy it!

i understand how object in java internally represented consisting of "pointers" fields , functions in vtables , how these internal representations change when there assignments, implicit casts , explicit casts done, , how static , dynamic type checking works. consider example extended from: dynamic method dispatch in java class a{ int a=10; public void show(){ system.out.println("show a: "+a); } } class b extends a{ public int b=20; public void show(){ system.out.println("show b: "+b); } } class c extends b{ public int c=30; public void show(){ system.out.println("show b: "+c); } } how objects constructed in memory? happens when there assignment (or equivalently parameter passed)? difference in memory-represenation of object in following cases? b bobj = new b(); aobj = new b(); c cobj = new b(); what happens in memory-representation when there explicit up/down casting? how check if such cast a
