Construct a directed graph of containing all characters as vertices. Create an edge from each character to each character directly following that character in any word. For example, if you have a word @ % ^, you’d have edges @ -> % and % -> ^. Run a topological sort on the graph to get … Read more
supposing head is the index where you place a new value, when you push a value temp.head++;must be replaced by temp.head = (temp.head + 1) % BUFFER_LENGTH; to manage the length of the buffer. You also have to move the tail when the buffer is full. I do not understand why you push 1 value … Read more
What is length? length does not exist, but Node.length does. The reason return(1+length(self.next)) doesn’t work is because you’re calling length(), not Node.length(). Instead, try this: return(1+LinkedList.length(self.next)) Or this (my preference): return(1+self.next.length()) solved Why isn’t length(self.next) a valid expression in python? [closed]
You can impose a tree structure on an array. The leaves of the tree are the array itself. The next level up has one node for each pair of array elements. The next level up has four descendants for each node, and so on… 15 13 14 9 10 11 12 1 2 3 4 … Read more
Since you want the thread to wait for an answer, I’d suggest creating a question object that has the question text, can store the answer, and has a CountDownLatch for tracking when the answer is available. public final class Question { private final String question; private String answer; private CountDownLatch latch = new CountDownLatch(1); public … Read more
All you have to do is just adding a single line after the do-while loop as follows: do { cout << temp->data << “->”; temp = temp->link; } while (temp != front); cout<< front->data << “->”; assuming front is the head of your linked-list. Now I’ve a question for you, what you gonna do if … Read more
ArrayMap keeps its mappings in an array data structure — an integer array of hash codes for each item, and an Object array of the key -> value pairs. Where ArrayList is a List. Resizable-array implementation of the List interface. Implements all optional list operations, and permits all elements, including null. FYI ArrayMap is a … Read more
Just a small improvement based on your code to find limit primes instead of limit numbers. limit = 1000 def is_prime(n): for i in range(2, n): if n%i == 0: return False return True sum = 0 num = 2 for i in xrange(limit): while not is_prime(num): num += 1 sum += num num += … Read more
I continued to search for a specific definition from past reputable sources to confirm what I had suspected, and I’m writing to provide my findings. Perhaps the most significant is the official paper defining PATRICIA, published by DR Morrison in October 1968s “Journal of the ACM”: PATRICIA evolved from “A Library Automaton” [3] and other … Read more
Why isn’t std::set just called std::binary_tree? Because Tree doesn’t describe how the interface is used. Set does. std::set does not provide sufficient operations to be used as a general purpose search tree. It only provides an interface to a particular application of a search tree: The representation of a set. Technically the standard doesn’t specify … Read more
An approach should consider breaking the OP’s entire task into two separate ones. Within an intermediate step one firstly does reduce the list of material items into a map of (grouped) material items. The final step does a map–reduce on the values of the intermediate result, where the reduce task is responsible for summing up … Read more
The compiler assigns offsets to all members, and includes these in all load/store operations on members: struct foo { uint32_t bar; uint32_t baz; uint32_t get_baz() { return baz; } }; uint32_t get_baz_from_foo(foo *f) { return f->baz; } becomes (ARM assembler code used for simplicity): foo__get_baz: ; calling convention: this pointer in r3 ; load 32 … Read more
Take a look at SPL: this provides linked lists for PHP, together with other data structures such as heaps, stacks and queues 1 solved Where can I find resources for PHP implementation of linked list data structure? [closed]
First, here’s the solution based on this answer: https://stackoverflow.com/a/57344801/3807365. Explanation below. const paths = [“src”, “src/components”, “src/components/index.ts”, “src/utils”, “src/configuration/config.ts”, “another/file.ts”]; let agg = { temp: [] }; paths.forEach(path => { path.split(“https://stackoverflow.com/”).reduce((agg, part, level, parts) => { if (!agg[part]) { agg[part] = { temp: [] }; agg.temp.push({ id: parts.slice(0, level + 1).join(“https://stackoverflow.com/”), level: level + 1, … Read more
You’re incorrectly printing the node’s value twice. You don’t need to check node->mid, as this is checked inside inorder(node->mid);. inorder(node) { if (node) { inorder(node->left); print(“%d “, node->value); inorder(node->mid); inorder(node->right); } } 0 solved Recursive and non-recursive traversal of three degree tree
