This function is used to insert new element at the end of deque.Syntaxdequename.emplace_back(value)ParameterValue − It defines the element to be inserted at the end of deque.ExampleInput Deque − 11 12 13 14 15Output New Deque − 11 12 13 14 15 16Input Deque − M O M E N TOutput New Deque − M O M E N T SApproach can be followedFirst we declare the deque.Then we print the deque.Then we define the emplace_back( ) function.Then we print the new deque after inserting new element.By using above approach we can enter new element at end. While defining function we ... Read More

Given is the task to show the functionality of deque emplace_front( ) and deque emplace_back( ) function in C++ STLWhat is DequeDeque is the Double Ended Queues that are the sequence containers which provides the functionality of expansion and contraction on both the ends. A queue data structure allows users to insert data only at the END and delete data from the FRONT. Let’s take the analogy of queues at bus stops where the person can be inserted to a queue from the END only and the person standing in the FRONT is the first to be removed whereas in ... Read More

The deque back( ) function is used to reference last element of deque.Syntaxdequename.back( )ExampleInput Deque − 11 12 13 14 15Output New Deque − 15Input Deque − C H O I C EOutput New Deque − EApproach can be followedFirst we declare the dequeThen we print the deque.Then we define the back( ) function.By using above approach we can fetch the last element of the deque.Example// C++ code to demonstrate the working of deque back( ) function #include #include Using namespace std; int main( ){    // initializing deque    deque deque ={ 14, 15, 16, 17, 18 };    cout

Given is the task to show the functionality list insert( ) function in C++ in STL.What is List in STLList are containers that allow constant time insertion and deletion anywhere in sequence. List are implemented as doubly linked lists. List allow non-contiguous memory allocation. List perform better insertion extraction and moving of element in any position in container than array, vector and deque. In List the direct access to the element is slow and list is similar to forward_list, but forward list objects are single linked lists and they can only be iterated forwards.What is insert( )The list insert( ) ...

In analyzing data or processing data using python, we come across situations where the given list has to be remodeled or reshaped to get lists with different columns. We can achieve that with multiple approaches as discussed below.Using SlicingWe can slice the list at certain elements to create the columnar structure. Here we convert the given list into a new list where the elements are split form the middle. We sue two for loops. The outer one splits the elements from the zeroth element to the second element and the inner one from the second element to the last.Example Live Demox ... Read More
