This is an artist’s impression of the first confirmed detection of a star system that will one day form a kilonova — the ultra-powerful, gold-producing explosion created by merging neutron stars. These systems are so phenomenally rare that only about 10 such systems are thought to exist in the entire Milky Way. Credit: CTIO/NOIRLab/NSF/AURA/J. da Silva/Spaceengine/M.

A team of astrophysicists has discovered a binary pair of ultra-cool dwarfs so close together that they look like a single star.They're remarkable because they only take 20.5 hours to orbit each other, meaning their year is less than one Earth day. They're also much older than similar systems.We can't see ultra-cool dwarf stars with the naked eye, but they're the most numerous stars in the galaxy. They have such low masses that they only emit infrared light, and we need infrared telescopes to see them.They're interesting…

Given an integer n. There is a complete binary tree with 2n – 1 nodes. The root of that tree is the node with the value 1, and every node with a value x has two children where the left node has the value 2*x and the right node has the value 2*x + 1, you are given K queries of type (ai, bi), and the task is to return the LCA for the node pair ai and bi for all K queries.Examples:Input:  n = 5, queries = Complete binary tree for given input n=5Output:  Input:  n = 3, queries = Complete binary tree for given input n=3Output:…

Given an array of integer nums and a positive integer K, the task is to find the maximum number of integers that can be selected from the array such that the sum of the number of 1s in their binary representation is at most K.Examples:Input: nums = , K = 3Output: 2Explanation: The maximum number of integers that can be selected is 2 since the sum of the number of 1s in the binary representation of 3 and 4 is 3, which is equal to K.Input: nums = , K = 5Output: 4Explanation: The maximum number of integers that can be…

A binary Search Tree is a node-based binary tree data structure. We can perform preorder, in-order, and post-order…

In a recent study published in Astronomy and Astrophysical Letters, a team of researchers at the Massachusetts Institute of Technology (MIT) used various computer models to examine 69 confirmed binary black holes to help determine their origin and found their data results changed based on the model's configurations.Essentially, the input consistently altered the output, and the researchers wish to better understand both how and why this occurs and what steps can be taken to have more consistent results."When you change…

Given an array of characters arr of size N, whose each character is either ‘&’ (Bitwise AND) or ‘|’ (Bitwise OR). there are many possible ways of having a binary array of size N+1. Any of these arrays (say X) is transformed to another array Y by performing the following operationsY = X.for every i ( i from 1 to N-1) Y = (Y  & X)  if arr is ‘&’ and Y = (Y | X) if arr is ‘|’.The task is to find how many arrays are there which can be transformed to array Y such that the last element is 1.Examples :Input: arr =…

We commonly refer to them as the left and right child as each element in a binary tree may only have two children.What is a Full Binary Tree?A full binary tree is a binary tree with either zero or two child nodes for each node. A full binary tree, on the other hand, does not have any nodes that have only one child node.Full Binary TreeFull Binary…

Improve Article Save Article Like Article Improve Article Save Article Given a Binary Array arr, the task is to count the number of inversions in it. The number of inversions in an array is the number of pairs of indices i, j such that i < j and a > a.Examples:Input: arr = {1, 0, 1, 0, 0, 1, 0}Output: 8Explanation: Pairs of the index (i, j) are (0, 1), (0, 3), (0, 4), (0, 6), (2, 3), (2, 4), (2, 6), (5, 6).Input: arr = {0, 1}Output: 0Approach: Follow the below steps to solve the problem:Initialize the variable…
