What is time complexity of following code : int count = 0; for (int i = N; i > 0; i /= 2) { for (int j = 0; j < i; j++) { count += 1;
What is the most concise and efficient way to find out if a JavaScript array contains a value? This is the only way I know to do it: function contains(a, obj) {
I have a k*k squared matrix with diagonal elements x>0 and all other elements y>0. The values of k, x, y are all subject to change. Now I need the determi
I am learning about time complexity now, and I am working with BST (Binary Search Trees). This question needs some context and this is a follow up post to this
I heard the calculation amount of map function is O(1). But I can't understand the reason.
I can't think of an algorithm for my code. Please help me out. We have two files. The first one has text (Text length is n-words). The second
I'm currently taking algorithms and data structure. After nearly two months of studying, I still find time complexity extremely confusing. I was told (by my pr
Summary) What's the time complexity of math.prod() How to improve this code to get to the pass Details) Currently working on 'Product of Array Except Self' on L
As a small example, say I have N=6 elements { 0.03, 0.25000039, 1.391, 500.1, 0.5000001, 1.75001 } and K=3 then the combination { 0.25000039, 0.5000001, 0.
This is the Daily Coding Problem: “Given a singly linked list and an integer k, remove the kth last element from the list. k is guaranteed to be smaller
Let's say I have a matrix X with n, m == X.shape in PyTorch. What is the time complexity of calculating the pseudo-inverse with torch.pinverse? In other words,
I have written the algorithms for recursive and iterative binary search: Recursive AlgorithmBinSrch(a, i,l,x) // Given an array a[i :l] of elementsin nondecre
I'm doing this question in Leetcode : https://leetcode.com/problems/word-ladder/ My solution was a BFA approach, and only one nested loop: def ladderLength(self
Prove that 1 + 1/2 + 1/3 + ... + 1/n is O(log n). Assume n = 2^k I put the series into the summation, but I have no idea how to tackle this problem. Any he

for(int i = 0; i < n; i++) { for(int j = 0; j < i; j++){ // do swap stuff, constant time } } I read that single for loop is O(N) and trav
What is O(log(n!)) and O(n!)? I believe it is O(n log(n)) and O(n^n)? Why? I think it has to do with Stirling Approximation, but I don't get the explanation v
I am working on leetcode algorithm problem 977. Squares of a Sorted Array. Why the submissions using built-in method sorted is faster than my
I am curious. What is the correct way to describe this using Big-O Notation? var prices = [100, 180, 260, 590, 40, 310, 535, 10, 5, 3]; var biggest_profit = 0;
I'm wondering how sorting with an index actually works in MongoDB. There are a couple articles in the MongoDB documentation, but they don't actually describe ho
