The union of two sets is created by the elements that are present in either one of the sets, or in both. Elements from the second set that has the same element in the first set are not copied to the resulting set.Common set operations are −Set UnionSet IntersectionSymmetric Set Difference or Exclusive-ORSet Difference or SubtractionAlgorithmBegin    Declare set vector v and iterator st.    Initialize st= set_union (set1, set1 + n, set2, set2 +n, v.begin()))    Print the elements. End.Example Code Live Demo#include #include #include using namespace std; int main () {    int set1[] = {5, ... Read More

This is a c++ program to implemet set_symmetric_difference. The symmetric difference of two sets is built by the elements that are present in one of the sets, but not in the other.Common set operations are −Set UnionSet IntersectionSymmetric Set Difference or Exclusive-ORSet Difference or SubtractionAlgorithmBegin    Declare set vector v and iterator st.   Initialize st = set_symmetric_difference (set1, set1 + n, set2, set2 +n, v.begin()))    Print the elements obtained after symmetric_difference of two sets End.Example Code#include #include #include using namespace std; int main () {    int set1[] = {5, 6, 7, 8, 9, 10};   ...

The intersection of two sets is formed only by the elements those are common in both sets. The elements copied by the function come always from the first set in the same order. The elements in the both the sets shall already be ordered.Common set operations are −Set UnionSet IntersectionSymmetric Set Difference or Exclusive-ORSet Difference or SubtractionAlgorithmBegin    Declare set vector v and iterator st.    Initialize st = set_intersection (set1, set1 + n, set2, set2 +n, v.begin()))    Print the intersection between two sets.

Set is abstract data type in which each element has to be unique, because the value of the element identifies it. The value of the element cannot be modified once it is added to the set, but it is possible to remove and add the modified value of that element.Functions and descriptions:Functions used here:    st.size() = Returns the size of set.    st.insert() = It is used to insert elements to the set.    st.erase() = To delete the element from the set.    st.find() = Returns an iterator to the search element in the set if found, else ...

A queue is a linear structure which follows First In First Out (FIFO) order in which the operations are performed on the elements of the queue.AlgorithmFunctions used here:    q.size() = Returns the size of queue.    q.push() = It is used to insert elements to the queue.    q.pop() = To pop out the value from the queue.    q.front() = Returns the front element of the array.    q.back() = Returns the back element of the array.Example Code#include #include #include #include using namespace std; int main() {    queue q;    int c, i;    while (1) {       cout

To create KeyValue tuple from another collection, use the fromCollection() method. We will be creating the tuple from List collection. Let us first see what we need to work with JavaTuples.
