Distributing all balls without repetition in C++ Program
In this tutorial, we are going to learn how to distribute n balls for k students without hurting anyone.The idea is simple, we have n balls in different colors that need to be distributed to the students. We don't have to give more than one ball of the same color to any student. If it is possible for a student to get more than one ball of the same color, then distribution should not happen.Let's see an example.Inputn = 10 k = 5 ballsColors = "rrrgbrbgbr"OutputYesNo color is more than the number of students (k). So, no student will get ...
Read MoreDensity of Binary Tree in One Traversal in C++ Program
In this tutorial, we are going to learn how to find the density of the binary tree in a single traversal.The density of the binary tree is obtained by dividing the size of the tree by the height of the tree.The size of the binary tree is the total number of nodes present in the given binary tree.The height of the binary tree is the max depth of the leaf node from the root node.Let's see the steps to solve the problem.Initialize the binary tree dummy data.Find the size and height of the tree.Recursively count the height of the tree.Return ...
Read MorePrinciples of Risk Management and Paradigm in C++
Risk Management is the approach that is used to manage all available resources and make the best use of the resources available in the system.The project manager will analyse risks from all categories and there might be some risks in the working of the project in the runtime environment.Principles of Risk ManagementThere are 5 basic principles of Risk management. They are:GLOBAL PERSPECTIVE: This risk analysis of software in context of system and business problems planned to be solved. This analysis takes underconsideration the larger system definition, design and implementation.FORWARD LOOKING VIEW: This analysis considers all possible solutions to future risks to the product. Here, ...
Read MoreFile opening modes(r versus r+) in C++
File handling in programming languages is very important for the interaction of programming with the memory for accessing files and fetching data in it.Using a program, you can read data from a file as well as write data to the file and do a lot more functions.Here, we will see reading of data from a file.In programming, before performing any operation you need to open the file. And there are multiple modes to open a file in the programming language. The access to the file is based on the mode it is opened with.Here we will learn about the difference between ...
Read MoreFile globbing in Linux in C++
p>File globbing also known as Path Name Expansion. It is the method of recognizing wildcard patterns in linux and then finding the file path expansion based on these patterns.Wildcard Patterns are strings that are used for selection of multiple files based on patterns.The character patterns like “?” , “[ ]” , “*” are used for pattern matching and multiselection of the files.Example of wildcard characters using in file globbing:Asterisk (*) : the * pattern is used when we need to match 0 or more character after the string in the filename.For example: file* will match all files with name file, files, file2, or with anything ...
Read MoreFederated database management system issues in C++
Database Management System or DBMS in short refers to the technology of storing and retrieving usersí data with utmost efficiency along with appropriate security measures.Federated Database management system is a special type of DBMS in which transparently maps more that one autonomous database into one database which is federated database.The federated database management system is useful while working with multiple applications that uses federation of databases.There are some issues with the federated database management system. They are −Managing the difference in data models, while working with federated databases multiple applications can have different type of data models and dealing with these ...
Read MoreExtended Operators in Relational Algebra in C++
Relational data model is the primary data model, which is used widely around the world for data storage and processing. This model is simple and it has all the properties and capabilities required to process data with storage efficiency.They are basic operators on Relation Algebra, here we will learn about some extended operators. They are mainly of three types:Intersection Join Divide Intersection Operation i s a special type of operation in for relations R1 and R2 where the relation in which the tuples with elements present in both relations i.e. in relation R1 and R2. JOIN Conditional Join is a special type of join in which we ...
Read MoreExternal Sorting with Example in C++
External Sorting is a category of sorting algorithm that is able to sort huge amounts of data. This type of sorting is applied on data set which acquire large memory which cannot be holded in main memory (RAM) and is stored in secondary memory ( hard disk).The idea of sorting used in external sort is quite similar to merge sort. In also possess two phases like in merge sort, In the sort phase, small memory size data sets are sorted and then in merge phase, these are combined to a single dataset.External Sorting For a huge data set which cannot be processed in ...
Read MoreEndian order and binary files in C++
In the binary file and data management, endianness is the sequence of bytes of a digital data inside the computer memory.In computer memory there are two type of endian order,Big-endian system stores the most significant byte of the data.Small-endian systems store the least significant byte of the data.
Read MoreEditors and Its types in System Programming in C++
Editors are basically computer programs that are utilised to edit files on a computer. The provide environment to a programmer to create, edit, update, format a document in any order he/she wants to.In system programming or programming, editors are software or tools that are used to edit the program. These are basically text editors of special type that have integrated functionality to edit code.Some common program editors are notepad++, visual code, sublime. Also there are some edits that provide things used to do more than just editing the code. They are the integrated development environment (IDE) which can help you edit, debug and run ...
