In this article, we are given a mathematical series (1^1 + 2^2 + 3^3 + … + n^n) defined by a number n which defines the nth terms of the series. This series can be represented mathematically as: $$ \displaystyle\sum\limits_{k=1}^n k^k $$ The ... Read More

What is Cycle Sort? Cycle sort is an in-place, unstable sorting algorithm. It is a comparison sort that is theoretically optimal in terms of the total number of writes to the original array, unlike any other in-place sorting algorithm. A sorting algorithm is in-place sorting in which the sorted items ... Read More

In this article, we will implement a C++ program to find whether a number is a power of two. So, you are given a positive integer n; the task is to find if the given number is a power of 2 or not. Let's see some of the numbers that ... Read More

What is Linear Search? Linear search is a sequential searching technique in which we start at one end of the list or array and look at each element until the target element is found. It is the simplest searching algorithm, with O(n) time complexity. Example Scenario let's see the following ... Read More

The mutable keyword in C++ is a storage class specifier. It enables non-static, non-const, and non-reference data members (i.e., mutable data member) of a class to be changed even when the object containing them is declared constant. Mutable data members are those members whose values can be changed in runtime ... Read More

Binary search is the fastest algorithm for finding an item from a sorted list of items. C++ STL provides built-in functions to perform binary search operations on sorted ranges of elements. In this article, we will learn binary_search, lower_bound and upper_bound functions in C++ STL. First of all, let's understand ... Read More

In this article, we'll show how to add two numbers using C++ and display the result. Adding two numbers is a basic arithmetic operation, meaning we combine their values to get a total. We will see different methods to solve this. Different Ways to Add Two Numbers in ... Read More
