first of all, learned that: you cannot instantiate interface an interface doesn't implement functions after seeing following java code: public class myclasstest { public static void main(string[] args) { // string charsequence? charsequence c = "java"; system.out.println(c); system.out.println(c.length()); } } i confused when learned charsequence interface how can use interface object , initialize it? why charsequence implements length function if interface? "java" instance of string class, implements charsequence interface, includes implementing length() method. therefore can assign charsequence variable. a variable type interface can assigned references instances (objects) of classes implement interface.

i've got little problem rotate3d. on fiddle: https://jsfiddle.net/c3snpkpr/ the problem is, if hover on <div> from left or right, works , bugging , rotating more or less given 180deg. <div> corners same. how can avoid this? what happens when hover element, mouse pointer kind of end outside when animates (the element loose mouse capture), , when, moves if have taken pointer outside yourself. use wrapper element ( fiddle demo ) or pseudo (below sample) div { width: 150px; height: 150px; margin-right: 20px; } div:after { content: ''; display: block; background: green; width: 150px; height: 150px; transition: 1s; transform: rotate3d(0, 1, 0, 0deg); border-radius: 50%; border: 5px solid red; } div:hover:after { background: red; transition: 1s; border: 5px solid green; transform: rotate3d(0, 1, 0, 180deg); } <div></div>

given vector double values. want know distances between elements of vector have similar distance each other. in best case, result vector of subsets of original values subsets should have @ least n members. //given vector<double> values = {1,2,3,4,8,10,12}; //with simple values example //some algorithm //desired result as: vector<vector<double> > subset; //in case of above example expect result like: //subset[0] = {1,2,3,4}; //distance 1 //subset[1] = {8,10,12}; //distance 2 //subset[2] = {4,8,12}; // distance 4 //subset[3] = {2,4}; //also distance 2 not connected subset[1] //subset[4] = {1,3}; //also distance 2 not connected subset[1] or subset[3] //many others if n 2. if n 3 (normally minimum) these small subsets should excluded. this example simplified distances of integer numbers iterated , tested vector not case double or float. my idea far i thought of calculating distances , storing them in vector. creating difference distance matrix , thres...
