问题 This question already has answers here : Initialize a nested struct (8 answers) Closed 4 years ago . Hi I am very new to Golang, please help me. I have defined a struct inside a struct. But I get an error when I try to initialise the main struct. type DetailsFilter struct { Filter struct { Name string ID int } } var M map[string]interface{} M = make(map[string]interface{}) M["Filter"] = map[string]interface{}{"Name": "XYZ", "ID": 5} var detailsFilter = DetailsFilter{Filter: M["Filter"]}} The

问题 I am having troubles when I try to deserialize one Json string with Gson. The string goes something like this (Note: I just simplified it, but leaving the part I am having troubles with and because of that, there might be Json syntaxis errors, but I have checked with an online validator that the string I am working with is OK): // let's call this "container" json element { "context": "context", "cpuUsage": cpuUsageValue, "name": "thename", "rates": { "definition": [ { "key": "name", "type":

问题 I'm trying to loop through one array, adding a new level to another array each time. Let me illustrate - variable $arr's values are different each time $arr = array("1","5","6"); Looping $index[$arr[0]]; Looping $index["1"][$arr[1]] // "1" since this key was filled in by the previous loop, continuing with a new key Looping $index["1"]["5"][$arr[2]] // same as previous loop --looped over all $arr's items, done, result is $index["1"]["5"]["6"]-- The problem is I won't know how much values the

问题 Im trying to write a function that takes a list and can print the lowest integer that is within that list. Now i'm trying to figure out what to do where this works with nested lists that if the lowest number is within one of those nested lists then overall it will print that number. My code is here: def listMin(): list2 = [3,4,[2,99,8],7] for i in range (len(list2)): if type(list2[i]) == type([]): y=min(i) list2.append(y) print "hello" if len(list2)== 0: return None else: x= min(list2) print

问题 Before asking this, I have read this question , which is similar to mine. Here I will provide my program in detail. #define N 70000 #define M 1000 class ObjBox {public: int oid; float x; float y; float ts}; class Bucket {public: int bid; int nxt; ObjBox *arr_obj; int nO;} int main() { Bucket *arr_bkt; cudaMallocManaged(&arr_bkt, N * sizeof(Bucket)); for (int i = 0; i < N; i++) { arr_bkt[i].bid = i; arr_bkt[i].nxt = -1; arr_bkt[i].nO = 0; cudaError_t r = cudaMallocManaged(&(arr_bkt[i].arr_obj)

问题 I have a list: l = [['en', 60, 'command'],['sq', 34, 'komand']] I want to search for komand or sq and get l[1] returned. Can I somehow define my own matching function for list searches? 回答1: An expression like: next(subl for subl in l if 'sq' in subl) will give you exactly the sublist you're searching for (or raise StopIteration if there is no such sublist; if the latter behavior is not what you want, pass next a second argument [[e.g, [] or None , depending on what exactly you want!]] to

问题 You can forward declare a template inner class inside a normal class, and use the defined type as any other forward declared type. class Outer { template <int N> class Inner; typedef Inner<0> Inner0; Inner0* f(); }; template<int N> class Outer::Inner {}; Now if Outer is itself a template class, is there a way to keep the declaration of Inner outside the declaration of Outer ? Something like : template<typename T> class Outer { template <int N> class Inner; typedef Inner<0> Inner0; Inner0* f()

问题 I'd like some help please. I have created dynamic a menu navbar that displays the menu items accoridning to the order that I've set them. I'm using this nestedsortable plugin, to order my menu items, but currently my menu has only 2 levels, so basicly it goes like this: Item1 Item2 > Subitem2.1 > Subitem2.2 Item3 etc etc. What I'd like to do is make it with n-levels, so basicly something like this: Item1 Item2 > Subitem2.1 >> Subitem2.1.1 > Subitem2.2 Item3 etc etc. and each item can go n

问题 I am trying to create a hive table with nested Collection items. Suppose I have an array of struct. CREATE TABLE SAMPLE( record array<struct<col1:string,col2:string>> )row format delimited fields terminated by ',' collection items terminated by '|'; First level, the separator ',' will override the default delimiter '^A'. Second level, the separator '|' will override the default second level delimiter '^B' to separate out the outer most structure (i.e. Array). Third level hive will use the
