What is a Binomial Tree?Binomial tree is an ordered tree data structure, let's say, B0 consists of a single node whereas a binomial tree represented as Bk consists of two binomial trees i.e. Bk-1 which are linked together. The root of one binomial tree is the leftmost child of the root of the other binomial tree. Binomial tree is mostly used for fundamental and technical analysing of assets or the stocks.The nodes of a binomial tree represent the intrinsic value of an asset. It helps investors or buyers of the markets to analyze the right time and value for investment.What ... Read More

Given an array Arr[] containing N elements. The goal is to find the minimum and maximum value from indexes of query.According to the query we are given starting index and ending indexes.For ExampleIn − Arr[] = { 1, 2, 3, 4, 5 } QStart = 1 QEnd = 4Out −Minimum Value : 2Maximum Value : 5Explanation −In the above queries the starting index is 1 and ending index is 4. Between these two indexes, minimum value in Arr is 2 and maximum value is 5In − Arr[] = { 10, 12, 3, 2, 5, 18 } QStart = 2 QEnd = 5Out −Minimum Value : ... Read More

The C++ Standards committee is always focusing on shipping new features every three years. The two main parts of the specification are the core functionality of the programming language and the Standard Template Library (STL). The new features are introduced to make the code cleaner, easier and compact. Following is the list of features that are introduced-:1. Fold ExpressionsFold expressions are used to write shorter codes for a variable number of arguments that can be passed to a function or can be returned from the function. It enables the use of any number of variables as arguments and in return ... Read More

A 2-3 Tree is a type of tree in data structures in which every node of the tree is either a 2 nodeor 3 nodes. It is a special type of B-Tree with order 3.A 2 node in the tree is one which has one data part and two child nodes.A 3 node in the tree is one which has two data parts and three child nodes.Fig:- A 2-3 treeProperties of a 2-3 Tree:-Every internal node is either a 2 node or a 3 node.A node containing one data part can be a 2 node with exactly 2 children or ...

We are given an array Arr[] containing integer values. The goal is to find the maximum number of subarrays with XOR as 0. The bits of any subarray can be swapped any number of times.Note:- 1

We are given an array Arr[] containing integers and 2D array Q containing queries. Each query contains 3 values that are lpos, rpos and K. One can move from index i to next index i+1 in a single step or remain in that index. One can move from lpos to rpos in a maximum of K steps only. Add all numbers at each step including the leftmost number. The goal is to maximize the sum in maximum K moves. If no movement is possible from lpos to rpos in K steps then print “No”. Let us understand more.Let us see ... Read More

We are given a cube which can be formed using a 3-D array as cube[length][breadth][height]. The task is to calculate the minimum sum path which will be achieved by traversing the cube and hence print the result.Let us see various input output scenarios for this -In − int cube[length][breadth][height] = { { {2, 4, 1}, {3, 4, 5}, {9, 8, 7}}, { {5, 3, 2}, {7, 6, 5}, {8, 7, 6}}, { {3, 2, 1}, {4, 3, 2}, {5, 4, 3}}}Out  − Minimum Sum Path In 3-D Array are: 15Explanation − we are given a cube having length, breadth and height. Now, we ... Read More

We are given integer values as a_num that will store the numerator and p_den that will store the denominator which should be a prime number. The task is to check whether the operations performed on a_num after dividing with p_den proves the midy’s theorem or not.Steps to prove Midy’s theorem are-Input numerator as a_num and denominator as p_den which should always be a prime value.Divide the numbers. Check for the repeating decimal values.Store the decimal values until they are not repeating.Check whether the digits are even, if yes, then break them into halvesAdd both the numbers. If the output is ... Read More

We are given with an array of integer elements of any given size. The task is to find the maximum sum which will be calculated by forming the subarrays from the given array within the given range which can be started from any possible index value in an array.Let us see various input output scenarios for this -In − int arr[] = { 3, 2, -1, 6, 7, 2 }, int first = 0, int last = 5Out − Maximum Subarray Sum in a given Range is: 19Explanation − we are given with an array containing both positive and negative values and a ...

To check if the given timestamp is on offset or not, use the CustomBusinessHour.is_on_offset() in Pandas. Pass the timestamp as an argument to check.At first, import the required libraries −import pandas as pdSet the timestamp object in Pandas −timestamp = pd.Timestamp('2021-11-14 05:20:30') Create the CustomBusinessHour Offset. CustomBusinessHour is the DateOffset subclass −cbhOffset = pd.tseries.offsets.CustomBusinessHour(start="09:30", end = "18:30")Add the offset to the Timestamp and display the Updated Timestampprint("Updated Timestamp...", timestamp + cbhOffset) Check if the given timestamp is on offset or not −offset = cbhOffset.is_on_offset(pd.Timestamp('2021-11-20 05:20:30'))Display the result −print("Check if the given timestamp is on offset or not...", offset) ExampleFollowing is ...
