nested

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

问题 I have created a couple of different structures in a program. I now have a structure with nested structures however I cannot work out how to initialize them correctly. The structures are listed below. /***POINT STRUCTURE***/ struct Point{ float x; //x coord of point float y; //y coord of point }; /***Bounding Box STRUCTURE***/ struct BoundingBox{ Point ymax, ymin, xmax, xmin; }; /***PLAYER STRUCTURE***/ struct Player{ vector<float> x; //players xcoords vector<float> y; //players ycoords

问题 I have a dictionary that I've converted to a list so I can sort by the first item. The key in the dictionary is a string (of numbers), the value is an integer which is maintained in the list. The list from the dictionary conversion looks like: [('228055', 1), ('228054', 1), ('228057', 2), ('228056', 1), ('228051', 1), ('228050', 1), ('228053', 1), ('203184', 6), ('228059', 1), ('228058', 1), ('89370', 2), ('89371', 3), ('89372', 2), ('89373', 1), ('89374', 1), ('89375', 1), ('89376', 1), (

问题 I want to be able to print a diamond like this when the user enters 5 for the diamond. But also will work for any value that is odd and greater than 0. I have a code that works to make a diamond for user input of 5 but won't work for all odd number inputs.. half = (size/2)+1; for (a=1; a <= half ; a++) /*top to mid row of diamond*/ { for (b=a; b<half;b++) { printf(" "); } for (c= size -2* a; c <= half; c++) { printf("*"); } printf("\n"); } for (a = 1; a < half;a++) { for (b = a; b>0;b--) {

问题 I have a set of list elements ( <li> within a <ul> ) laid out as bubbles on a chart like this, where the bubbles are the <li> elements: http://i.stack.imgur.com/PR7vR.png I want to be able to detect the difference between Moving the mouse from bubble #1 to the grid Moving the mouse from bubble #1 directly to another bubble, such as bubble 2 I've attempted to use $(this) in the .mouseleave() even for a bubble, but it registers the element that you're leaving rather than the element that you're

问题 I've have been building an analysis workflow for my PhD and have been using a triple nested list to represent my data structure because I want it to be able to expand to an arbitrary amount of data in its second and third levels. The first level is the whole dataset, the second level is each subject in the dataset and third level is a row for each measure that each subject. [dataset] | [subject] | [measure1, measure2, measure3] I am trying to map a function to each measure - for instance

问题 I was wondering if there's a simple way to combine the functions of rapply( , how = "replace") and mapply() , in order to use mapply() on nested lists recursively. For instance, I have two nested lists: A = list(list(c(1,2,3), c(2,3,4)), list(c(4,3,2), c(3,2,1))) B = list(list(c(1,2,3), c(2,3,4)), list(c(4,3,2), c(3,2,1))) Let's say I want to apply function(x, y) x + y to all the corresponding elements in A and B and preserve the nested structure. The desired result would be result = list

问题 <doc> <element> text <item> text1 </item> <item> text2 </item> text3 </element> <element> another text </element> ... </doc> And I want to extract text to an string like this: "text text1 text2 text3" "item" tags are nested inside "element" Im using xmlpullparser in Android but I could use any other parser if it make things easier. tx. 回答1: I parse similar xml files. Here is an example. You'll need to add error checking as appropriate. void loadXML(XmlPullParser xpp) { int eventType = xpp
