This article explains about-“Linux Package Management with Aptitude”What is APTapt is a command line package manager and provides commands for searching and managing as well as querying information about packages. It provides the same functionality as the specialized APT tools, like apt-get and apt-cache, but enables options more suitable for interactive use by default.]To get more information about APT, use the following command –$ aptThe sample output ...
Read MorePrint all the sum pairs which occur maximum number of times in C++
In this problem, we are given an array of n unique integers. And we have to find the sum of two integers of the array which has the maximum frequency. The problem has multiple solutions and you need to find them all.Input : array = { 1, 12, 5, 7, 9, 11} Output : 16 12Explanation − sum 16 and 12 occur two times.5 + 11 = 16 & 7 + 9 = 16 1 + 11 = 12 & 5 + 7 = 12Now to solve this problem, our approach to the problem is checking the occurrence every sum ...

Read MoreLearn Why ‘less’ is Faster Than ‘more’ Command for Effective File Navigation
More is a command to view (but not modify) the contents of a text file, one screen at a time. It is available on Unix and Unix-like systems, DOS, OS/2, and Microsoft Windows. Programs of this sort are called pagers. More is a very basic pager, originally allowing only forward navigation through a file, though newer implementations which allows for limited backward movement.The basics of more command should be like this –$ more /var/log/dkpg.logThe sample output should be like this –2016-12-02 11:30:45 startup archives unpack 2016-12-02 11:30:45 install python-ptyprocess:all 0.5-1 2016-12-02 11:30:45 status half-installed python-ptyprocess:all 0.5-1 2016-12-02 11:30:45 status ...
Read MoreHuffman Trees in Data Structure
DefinitionHuffman coding provides codes to characters such that the length of the code depends on the relative frequency or weight of the corresponding character. Huffman codes are of variable-length, and without any prefix (that means no code is a prefix of any other). Any prefix-free binary code can be displayed or visualized as a binary tree with the encoded characters stored at the leaves.Huffman tree or Huffman coding tree defines as a full binary tree in which each leaf of the tree corresponds to a letter in the given alphabet.The Huffman tree is treated as the binary tree associated with ...
Read MoreDictionary Operations in Data Structure
A dictionary is defined as a general-purpose data structure for storing a group of objects. A dictionary is associated with a set of keys and each key has a single associated value. When presented with a key, the dictionary will simply return the associated value.For example, the results of a classroom test could be represented as a dictionary with student's names as keys and their scores as the values:results = {'Anik' : 75, 'Aftab' :80, 'James' : 85, 'Manisha': 77, 'Suhana' :87, 'Margaret': 82}Main operations of dictionariesDictionaries typically support so many operations −retrieve a value (based on language, attempting to ...
Read MoreBayes’ Rule in Data Structure
A way to update our beliefs depended on the arrival of new, relevant pieces of evidence are provided by Bayes rule. For example, if we were trying to provide the probability that a given person has cancer, we would initially just conclude it is whatever percent of the population has cancer. However, given extra evidence such as the fact that the person is a smoker, we can update our probability, since the probability of having cancer is greater given that the person is a smoker. This allows us to utilize prior knowledge to improve our probability estimations.The rule is explained ...
Read MoreBoole’s Inequality in Data Structure
In probability theory, according to Boole's inequality, also denoted as the union bound, for any finite or countable set of events, the probability that at least one of the events happens is no higher than the sum of the probabilities of the individual events.In mathematics, the probability theory is denoted as an important branch that studies about the probabilities of the random event. The probability is denoted as the measurement of chances of happening an event which is an outcome of an experiment.For Example − tossing a coin is denoted as an experiment and getting head or tail is denoted ...
