Containers in C++ STL
The C++ STL (Standard Template Library) is a powerful set of C++ template classes to provide general-purpose classes and functions with templates that implement many popular and commonly used algorithms and data structures like vectors, lists, queues, and stacks.It is a library of container classes, algorithms, and iterators. It is a generalized library and so, its components are parameterized. Working knowledge of template classes is a prerequisite for working with STL.Templates are a feature of the C++ programming language that allows functions and classes to operate with generic types. This allows a function or class to work on many different ...
Read MoreMaximum Sum Decreasing Subsequence in C++
In this article, we are given an array arr[] of N integers. Our task is to find the Maximum Sum Decreasing Subsequence in C++. A Maximum Sum Decreasing Subsequence (MSDS) is a subsequence of a given sequence of array. Here the sequence elements are ordered in decreasing arrangement and the sum of these elements is the highest. Here, given a sequence of array a1, a2, …, an, the goal is to find a subsequence ai1, ai2, …, aik, where i1>i2>…>i1, such that we say the subsequence is ai1>ai2>…>aik (ordered in a decreasing order). The sequence of terms ai1+(ai2)...+(aik) is ...
Read MoreMaximum sum and product of the M consecutive digits in a number in C++
In this article, we are given a string representing a number. Our task is to create a program in C++ to find the maximum sum and product of M consecutive digits from the given number. We find all sequences of M consecutive digits and return the maximum sum and product. In mathematics, consecutive numbers are defined as those numbers that follow each other in increasing order from the smallest to the largest, with no missing numbers in between. This problem can be iterated through the string representation of the number, in other words, we consider consecutive segments of the length ...
Read MoreProgram to find the common ratio of three numbers in C++
In this article, Our task is to create a Program to find the common ratio of three numbers in C++. The common ratio of three numbers is usually the same ratio between two numbers multiplied by each other to get the next one. When a particular number of terms in progression or sequence are involved such as in the geometric progression, a common ratio can be easily found by dividing the term with the preceding term. For instance, if we have three numbers x, y, and z. then the common ratio r can be found as r = x:y = ...
Read MoreProgram to find sum of series 1 + 2 + 2 + 3 + 3 + 3 + .. + n in C++
In this article, we are given a number n that denotes the nth term of the series. Our task is to create a Program to find sum of series 1 + 2 + 2 + 3 + 3 + 3 + .... + n in C++. This series is different from the other because it include terms that are repeated according to their values. The series 1 + 2 + 2 + 3 + 3 + 3 + … + n consists of repeated terms that are repeated infinitely only by their value. Such illustration 1 comes once, ’2 twice’, ...
Read MoreProgram to find sum of given sequence in C++
In this article, we are given two numbers n and k representing a series. Our task is to create a program in C++ that finds the sum of the sequence given below: The input cycle is the process of adding up all the numbers in the given sequence to get a single output. The process of recursion is frequently used in mathematics and may be implemented with sequences namely the arithmetic ones ( each term is acquired by adding a constant difference between the previous one) and the geometric sequence ( where each term is multiplied by a constant ratio with the former term ...
Read MoreProgram to find smallest difference of angles of two parts of a given circle in C++
In this article, we will find the smallest difference in angles between two parts of a given circle using the C++ programming language. Before proceeding to the code, let’s first understand how we can calculate the angles to find the smallest difference between them. We are given the angles of all the pieces of the circle in the array. We have to join the pieces in such a way that the angle difference between the two pieces is the least. Let's go through the input and output scenario for better understanding. Here, we declare an array contianing three different angles ...
Read MoreProgram to find slope of a line in C++
In this article, we will learn how to find the Slope of a line using a program. But before we proceed into the program, let's first understand what the Slope of a line represents in mathematics and how to compute it using its mathematics formula in C++. In mathematics, the Slope of a line is a numerical value that measures the line’s steepness and direction. It indicates the rate at which the line ups or down as you move along it from left to right (or horizontally). Generally, it is denoted by the letter "m". In mathematics, the steepness refers to the slope or gradient of a line. In terms of mathematical, ...
Read MoreHow are Outliers Determined in Seaborn using Boxplot?
What are Outliers? Outliers are the data points or observations which are far from the other points in a dataset. Outliers are caused due to measurement error, data entry error or experimental error etc. Outliers can skew the dataset which effects in statistical analysis and can increase the standard deviation of the dataset further effecting model prediction. An outlier may be a valid data point or can be noise. For a better understanding let us look at an example scenario. Imagine you are collecting data of student's height (age between 9 to 12 years). Most of the students are around ...
Read MoreFibonomial coefficient and Fibonomial triangle
In this article, we will discuss about a special type of number called fibonomial coefficient and how does a fibonomial triangle looks like. We will also discuss the C++ code approach to print a fibonomial triangle with a given height. Let us first discuss that what is a fibonomial coefficient. Fibonomial Coefficient We can call a fibonomial coefficient a generalisation of well known terms namely , Fibonacci numbers and binomial coefficients. The Fibonacci numbers are a series of numbers in which, each number is the sum of the two preceding numbers (for example − 0, 1, 1, 2, 3, 5, ...
