The Set Symmetric Difference is an operation used to find all elements that are present in either of the sets but not in both. In this article, we will learn how to use the set_symmetric_difference algorithm from the Standard Template Library (STL) in C++ to find the symmetric difference of two sets. What is Set Symmetric Difference? The set symmetric difference is an arithmetic operation performed between two sets to find all elements that are present in either of the sets but not in both. In C++, we have set_symmetric_difference(), which is a built-in function provided by C++ STL ... Read More

The Set Intersection is an operation used to find all elements that are common in both sets. In this article, we will learn how to use the set_intersection algorithm from the Standard Template Library (STL) in C++ to find the intersection of two sets. What is Set Intersection? The set intersection is an arithmetic operation performed between two sets to find all elements that are common in both sets. In C++, we have set_intersection which is a built-in algorithm provided by C++ STL that computes the intersection of two sorted ranges of sets. That is, it returns the elements ... Read More

The Set Difference is an operation used to find all elements present in the first set but not in the second. In this article, we will learn how to use the set_difference algorithm from the Standard Template Library (STL) in C++ to find the difference of two sets. What is Set Difference? The set difference is an arithmetic operation performed between two sets to find all elements present in the first set but not in the second. In C++, we have set_difference which is a built-in algorithm provided by C++ STL that computes the set difference of two sorted ... Read More

Set is an associative container that stores unique elements in a sorted order. In this article, we will learn how to use the set container from the Standard Template Library (STL) in C++. What is Set? A Set is a container that stores data in a sorted order without any duplicates. Meaning, the duplicate values are automatically eliminated, and the elements are kept in ascending order by default. The STL library of C++ provides a pre-defined set container that uses a balanced binary search tree for storage. For example, in the code we have shown how data are ... Read More

Queue is a linear data structure that follows the First In First Out (FIFO) principle. In this article, we will learn how to use the queue container from the Standard Template Library (STL) in C++. What is Queue? A Queue is a container that stores data in a sequential way. Meaning, the data that is inserted first to the queue is the one to be removed first from it. This is same as a queue of people where, the person who comes first to the queue will served first. The STL library of C++ provides a pre-defined queue container ... Read More

Priority Queue is a special type of queue in which elements can be accessed based on their priority. In this article, we will learn how to use the priority_queue container from the Standard Template Library (STL) in C++. What is Priority Queue? A Priority Queue is a container that stores data in such a way that the highest (or the lowest) priority element will always at the front of queue. Meaning, a priority queue does not follow FIFO rule of a regular queue, it processes elements based on ceratin priority. This priority can be defined as highest elements at ... Read More

The Prev permutation is an algorithmic operation that rearranges the elements of an array or a range of an array into the previous lexicographically smaller permutation. In this article, we will learn how to use the prev_permutation() function from the Standard Template Library (STL) in C++. What is Prev Permutation? The Prev Permutation is an operation used to generate all the possible permutations of an array in reverse lexicographical order. A permutation is one of the N! arrangements of the elements in an array of size N. The STL library of C++ provide a pre-defined function for performing the ... Read More

A pair is a container provided by the Standard Template Library (STL) in C++ that stores two heterogeneous objects as a single unit. In this article, we will learn how to use a pair from the Standard Template Library (STL) in C++. What is Pair? Pair is a utility container defined in the header that is used to store two related data elements or objects in pairs. The first element will be referenced as first, and the second element will be referenced as second. It is commonly used to return two values from a function using a single ... Read More

Next permutation is an algorithmic operation that rearranges the elements of a range into the next lexicographically greater permutation. In this article, we will learn how to use the next_permutation() function from the Standard Template Library (STL) in C++. What is Next Permutation? The Next Permutation is an operation used to generate all the possible permutations an array in lexicographical order. A permutation is the one of N! arrangements of the elements in an array of size N. If the current sequence is the last permutation, the function transforms it into the first one (i.e., sorted in ascending order). ... Read More

A multiset is an associative container that stores data in a sorted order in such a way that it allows duplicate values in the set. In this article, we will learn how to use a multiset from the Standard Template Library (STL) in C++. What is Multiset? Multiset is a sorted associative container that allows storing multiple elements with the same value. The values are automatically arranged in sorted order. This makes it useful in scenarios where you need to keep count of repeated values while maintaining order. For example, we can store the scores of students even ... Read More
