sorting - d3.js sort descending positive to negative -

-

would sort largest positive largest negative.

desired output: (3,2,1,0,-1,-2,-3), current output: (3,2,1,0,-3,-2,-1)

initial array:

["-0.87", "0.51", "3.34", "1.58", "2.67", "0.51", "-1.58", "1.91", "-0.86", "-0.42", "0.23", "1.5", "-1.67", "1.9", "-2.88", "-0.63", "1.13", "-1.37", "-0.42", "-0.35", "-0.38", "0.65", "-0.41", "0.49", "1", "-0.14", "-0.07", "2.41", "3.09", "0.85", "0.51", "-0.67", "0.53", "0.98", "-0.88", "0.18", "-0.75", "-0.22", "-0.27", "-2.09", "0.01", "1.14", "-0.64", "-0.53", "3.01", "1.49", "1.56", "0", "0.67", "0.28", "-0.21", "-0.49", "-0.66", "-1.29", "0.67", "-0.76", "0.23"]

sorting code:

datapct.sort(d3.descending);

arranges like:

["3.34", "3.09", "3.01", "2.67", "2.41", "1.91", "1.9", "1.58", "1.56", "1.5", "1.49", "1.14", "1.13", "1", "0.98", "0.85", "0.67", "0.67", "0.65", "0.53", "0.51", "0.51", "0.51", "0.49", "0.28", "0.23", "0.23", "0.18", "0.01", "0", "-2.88", "-2.09", "-1.67", "-1.58", "-1.37", "-1.29", "-0.88", "-0.87", "-0.86", "-0.76", "-0.75", "-0.67", "-0.66", "-0.64", "-0.63", "-0.53", "-0.49", "-0.42", "-0.42", "-0.41", "-0.38", "-0.35", "-0.27", "-0.22", "-0.21", "-0.14", "-0.07"]

you're trying sort strings , that's why you're getting unexpected results. can see have array of strings they're in quotes.

to fix need convert string number can snippet:

datapct.foreach(function (d,i) {   datapct[i] = +d; });

there discussion converting strings number in api documentation such here.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
