WebIn Python, there’s a specific object in the collections module that you can use for linked lists called deque (pronounced “deck”), which stands for double-ended queue. collections.deque uses an implementation of a linked list in which you can access, insert, or remove elements from the beginning or end of a list with constant O (1) performance. WebAlgorithm of insert operation in the max heap. // algorithm to insert an element in the max heap. insertHeap (A, n, value) { n=n+1; // n is incremented to insert the new element A [n]=value; // assign new value at the nth position i = n; // assign the value of n to i // loop will be executed until i becomes 1. while(i>1) {
