## C++ Program to Calculate Area of Right Angle Triangle Updated on 09-Apr-2023 10:53:56
Introduction: In geometry, a triangle is a three-sided polygon with three angles. Right angle triangle is a special type of triangle which has one angle of 90 degrees. The area of a right angle triangle is half of the product of its base and height. In this article, we will discuss how to calculate the area of a right angle triangle using C++ programming language.  Problem Statement: Write a C++ program to calculate the area of a right angle triangle, given its base and height. Solution: To... Read More

## Count of permutations of size 2N with at least N increasing elements Updated on 01-Apr-2023 17:29:30
Permutations are arrangements of objects in a specific order. In mathematics, a permutation of a set is an arrangement of its elements, without repetition and order being important. Permutations play a significant role in various fields of mathematics, including combinatorics, group theory, and algebra. In this article, we will discuss the count of permutations of size 2N with at least N increasing elements and explain it with an example. C++ CODE // C++ implementation of the approach #includ...
