   • in querySelector: how to get the first and get the last elements? what traversal order is used in the dom?

     To access the first and last elements, try.

     var nodes = div.querySelectorAll('[move_id]');var first = nodes[0];var last = nodes[nodes.length- 1];-

     For robustness, add index checks.

     Yes, the order of nodes is pre-order depth-first. DOM's document order is defined as,

     There is an ordering, document order, defined on all the nodes in the document corresponding to the order in which the first character of the XML representation of each node occurs in the XML representation of the document after expansion of general entities. Thus, the document element node will be the first node. Element nodes occur before their children. Thus, document order orders element nodes in order of the occurrence of their start-tag in the XML (after expansion of entities). The attribute nodes of an element occur after the element and before its children. The relative order of attribute nodes is implementation-dependent.

     Adding to the answers here a solution (a bit different to the others proposed):

     Using the :last-of-type selector to get the last element of a certain specific tag name.

     Array method at()

     is also helpful in combination with querySelectorAll, but it requires to destruct the result, to get a "real" array, because querySelectorAll doesn't have the at method at its disposal (so sad...)

     console.log( ":last-of-type:", document.querySelector('mark:last-of-type') // <---- )-console.log( ":last-child:", document.querySelector('mark:last-child'))console.log( "querySelectorAll + at:", [...document.querySelectorAll('mark')].at(-1))

     <p>this is <mark>highlighted</mark> and this is <mark>is also</mark> but <strong>not this</strong>.</p>

   • In-order traversal of an AVL tree, saving the values in an array

     Top Answer

     Answered May 19, 2018 · 2 votes

     The big issue here is that your array indexing is wrong. Consider the in-order-traversal of an arbitrary node. You write everything under the left child starting from index y. Then you ignore what you just did, and write the current node's value at index y. Then, because you always increment y, it is possible that y > x at the point you check for y == x, and you write out-of-bounds.

     I would highly recommend solving this with an std::vector (whose data() member function can be used just like an array if you need that for further processing). That would also allow you to get rid of the length limitation:

     void inorder(Tree_Node* node, std::vector<int>& vector){ if (!node) return; inorder(node->getLeft(), vector); vector.push_back(GET_ID(node->getkey())); inorder(node->getRight(), vector);}

     However, if you have to use arrays (because manually implementing AVL trees is often done in education and some educators are crazy enough to demand that you don't use all the features available to you), you can still fix this by returning the current array index from the function:

     int inorder(int* array, Tree_Node* node, int size, int y = 0){ if (!node) return y; y = inorder(array, node->getLeft(), size, y); if (y >= size) return y; /* Check before you write! */ array[y++] = GET_ID(node->getkey()); return inorder(array, node->getRight(), size, y);}

   • What is the order in which the destructors and the constructors are called in C++

     Top Answer

     Answered Jul 09, 2015 · 80 votes

     The order is:

     • Base constructor
     • Derived constructor
     • Derived destructor
     • Base destructor

     Example:

     class B{public: B() { cout<<"Construct B"<<endl; } virtual ~B() { cout<<"Destruct B"<<endl; }};class D : public B{public: D() { cout<<"Construct D"<<endl; } virtual ~D() { cout<<"Destruct D"<<endl; }};int main(int argc, char **argv){ D d; return 0;}

     Output of example:

     Construct B

     Construct D

     Destruct D

     Destruct B

     Multiple levels of inheritance works like a stack:

     If you consider pushing an item onto the stack as construction, and taking it off as destruction, then you can look at multiple levels of inheritance like a stack.

     This works for any number of levels.

     Example D2 derives from D derives from B.

     Push B on the stack, push D on the stack, push D2 on the stack. So the construction order is B, D, D2. Then to find out destruction order start popping. D2, D, B

   • In what order does the Spring take the values in constructor-args

     Top Answer

     Answered Nov 01, 2019 · 4 votes

     A short answer: It takes arguments in the same order as they were described in the class constructor.

     A proof from Spring docs (p.7.4.1):

     Constructor argument resolution matching occurs using the argument’s type. If no potential ambiguity exists in the constructor arguments of a bean definition, then the order in which the constructor arguments are defined in a bean definition is the order in which those arguments are supplied to the appropriate constructor when the bean is being instantiated.

   • In-order traversal in BST-Ocaml

     Top Answer

     Answered Sep 29, 2016 · 4 votes

     When you're working with recursion you need to always reason as follows:

     • How do I solve the easiest version of the problem?
     • Supposing I have a solution to an easier problem, how can I modify it to solve a harder problem?

     You've done the first part correctly, but the second part is a mess.

     Part of the problem is that you've not implemented the thing you said you want to implement. You said you want to do a traversal and add the values to a list. OK, so then the method should take a list somewhere -- the list you are adding to. But it doesn't. So let's suppose it does take such a parameter and see if that helps. Such a list is traditionally called an accumulator for reasons which will become obvious.

     As always, get the signature right first:

     let rec in_order tree accumulator =

     OK, what's the easy solution? If the tree is empty then adding the tree contents to the accumulator is simply the identity:

     match tree with| Empty -> accumulator

     Now, what's the recursive case? We suppose that we have a solution to some smaller problems. For instance, we have a solution to the problem of "add everything on one side to the accumulator with the value":

     | Node (value, left, right) -> let acc_with_right = in_order right accumulator in let acc_with_value = value :: acc_with_right in

     OK, we now have the accumulator with all the elements from one side added. We can then use that to add to it all the elements from the other side:

     in_order left acc_with_value

     And now we can make the whole thing implement the function you tried to write in the first place:

     let in_order tree = let rec aux tree accumulator = match tree with | Empty -> accumulator | Node (value, left, right) -> let acc_with_right = aux right accumulator in let acc_with_value = value :: acc_with_right in aux left acc_with_value in aux tree []

     And we're done.

     Does that all make sense? You have to (1) actually implement the exact thing you say you're going to implement, (2) solve the base case, and (3) assume you can solve smaller problems and combine them into solutions to larger problems. That's the pattern you use for all recursive problem solving.

   What did the Romans know about Britain?

   • But to the Romans, Britain remained a great unknown. They knew about Gaul because of their Mediterranean connections; but they knew very little about Britain. In actual fact, even as Caesar began to conquer Gaul in the 50s BC, Britain was almost a terrifying place for the Romans. It was The North in ‘Game of Thrones’ about which they knew nothing.
