Introduction to Miscellaneous Problems
We have seen different problems in different sections. There are some other problems which are not categorized. In this section we will see some of the random problems. In this Section We are going to cover. Adding base n numbers Babylonian method to find the square root Factorial of a large number Check if a given point lies inside a Polygon Check Perfect Square or Not Check if given four points form a Square Check if two given sets are disjoint? Check if two line segments intersect Check whether a given point lies inside a Triangle Connect n ropes ...
Read MoreThe Best C++ IDE or Editor for Windows
The following are some of C++ IDEs for Windows. 1.Eclipse Galileo with CDT Plugin Eclipse is a well-known open source and cross platform IDE. It provides full functional C/C++ IDE with the following features − Code editor with support for syntax highlighting Support for folding and hyperlink navigation Source code refactoring plus code generation Tools for visual debugging such as memory, registers 2.NetBeans NetBeans is free, open source and popular IDE for C/C++. There are some following features − Support for automatic packaging of compiled application into .tar, .zip. Support for multiple compilers such as GNU, Clang/LLVM, ...
Read MoreIntroduction to Pattern Searching Algorithms
Pattern Searching algorithms are used to find a pattern or substring from another bigger string. There are different algorithms. The main goal to design these type of algorithms to reduce the time complexity. The traditional approach may take lots of time to complete the pattern searching task for a longer text. Here we will see different algorithms to get a better performance of pattern matching. In this Section We are going to cover. Aho-Corasick Algorithm Anagram Pattern Search Bad Character Heuristic Boyer Moore Algorithm Efficient Construction of Finite Automata kasai’s Algorithm Knuth-Morris-Pratt Algorithm Manacher’s Algorithm Naive Pattern Searching Rabin-Karp ...
Read MoreThe Best C++ Code Formatter/Beautifier?
There are so many C++ code formatter or beautifier tools which beautifies your code or format with proper indentation. The C++ code formatter/ beautifier are listed as follows − C++ Code Formatter/Beautifier Description Astyle This is a source code formatter. It can be used for C++, java and other languages. It’s latest version is 2.03 and it released in April 2013. Clang-Format It is a command line tool along with clang compiler. It is open- source tool and programmed in C++, python. The latest version is 3.3. Universal Indent GUI It ...
Read MoreHow do I get the current time zone of MySQL?
The following is the syntax to get the current time zone of MySQL. mysql> SELECT @@global.time_zone, @@session.time_zone; The following is the output. +--------------------+---------------------+ | @@global.time_zone | @@session.time_zone | +--------------------+---------------------+ | SYSTEM | SYSTEM | +--------------------+---------------------+ 1 row in set (0.00 sec) The above just returns “SYSTEM” because MySQL is set for system time zones. Alternately, we can get the current time zone with the help of now() function. Let us first ...
Read MoreIntroduction to Searching Algorithms
The searching algorithms are used to search or find one or more than one element from a dataset. These type of algorithms are used to find elements from a specific data structures. Searching may be sequential or not. If the data in the dataset are random, then we need to use sequential searching. Otherwise we can use other different techniques to reduce the complexity. In this Section We are going to cover − Binary Search Exponential Search Interpolation Search Jump Search Linear Search Ternary Search
Read MoreStack and Queue in Python using queue Module
In Python, it is very easy to implement stack and queue data structures. Stack is called LIFO because Stack works on the principle of "Last-in, first-out" and Queue is called FIFO because Queue works on the principle of "First-in, first-out", and the inbuilt functions in Python make the code shorter and simple. The Queue module implements multi-producer, multi-consumer queues and It is especially useful in threaded programming when information must be exchanged safely between multiple threads. The Queue class in this module implements all the required locking semantics and it depends on the availability of thread support in Python. This ...
Read MoreWhat is GRUB in Linux?
The GRUB (Grand Unified Bootloader) is a bootloader available from the GNU project. A bootloader is very important as it is impossible to start an operating system without it. It is the first program which starts when the program is switched on. The bootloader transfers the control to the operating system kernel. GRUB Features GRUB is the default bootloader for many of the Linux distributions. This is because it is better than many of the previous versions of the bootloaders. Some of its features are: GRUB supports LBA (Logical Block Addressing Mode) which puts the addressing conversion used ...
Read MoreIntroduction to Graph Algorithms
The graph is a non-linear data-structure, which consists finite number of nodes and a set of edges which are used to connect a pair of nodes. The graphs are used to solve some real-time problems to represent network etc. In different social networks, the graphs are used. In this Section We are going to cover − Bi-Connected Graph Checking Breadth First Search (BFS) for a Graph Bridges in a Graph Check if a given graph is tree or not Connectivity in a directed graph Depth First Search (DFS) for a Graph Detect Cycle in a an Undirected Graph Detect ...
Read MoreLoading Image using Glide in Android
Before getting into Glide example, we should know what is glide, Glide is an image processing library developed by muyangmin. Using glide library we can show image, decode images, cache images, animated gifs and many more.This example demonstrate about how to integrate glide in android.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code in build.gradle(Module:app).apply plugin: 'com.android.application' android { compileSdkVersion 28 defaultConfig { applicationId "com.example.andy.myapplication" minSdkVersion 15 ...
