nested

问题 I have a pretty complex data structure in my app, which I need to manipulate. I am trying to keep track of how many types of bugs a player has in thier garden. There are ten types of bugs, each with ten patterns, each pattern having ten colors. So there are 1000 unique bugs possible, and I want to track how many of each of these types the player has. The nested dictionary looks like: var colorsDict: [String : Int] var patternsDict: [String : Any] // [String : colorsDict] var bugsDict: [String

问题 Which is faster, successive for loops or a bunch of nested ones, for example, 3 successive for loops or 3 nested for loops? Will one always be faster than the other? 回答1: Successive loops will tend to be faster as long as there aren't too many. In a nested loop, for every increase in an argument n you could have an increase in time that is n squared. With successive loops any increase in n results in a linear change in execution time. 来源： https://stackoverflow.com/questions/37106754/faster

问题 I am trying to extract some information from a file that has the following content: field { a:"bb" c:"dd" field_param { x:"xx" y:"yy" } other_param { z:"ee" } abc_param { x: { abc: "value"; cfg:"value"} ze: "value" } } field { a:"bb" c:"dd" field_param { x:"xx" y:"yy" } others_param { z:"ee" } } There are more fields like above, in a text file. Not all the fields are the same format, some have different params. I am trying to extract for each field , to consider it as object with variables

问题 Is it possible to use document.writeln when trying to create a nested list? I am at the very very basic of learning javascript and don't know what I am doing wrong. I need to create a nested list using document.writeln, which seems to work. But, when I try to get it verified, a get a bunch of errors and it doesn't seem to be valid. Is it even possible to do what I am doing. For example. I have in the head (in the script area) something like: var number1 = {"Name": "Smith", "First Name": "John

问题 How do I convert an 'N' elements single dimensional array to 'N' level nested array in PHP ? Example: Input: $input = array('Orange','Apple','Banana'); Expected Output: $output = array( 'name' => 'Banana', 'sub_category' => array( 'name' => 'Apple', 'sub_category' => array( 'name' => 'Orange' ); This is my code: $categories = array('Orange','Apple','Banana'); $count = count($categories); for($i=0;$i<=$count;$i++){ if(isset($categories[$i+1])){ $parent = $categories[$i+1]; // parent
