Imagine stack in DS Algo as a pile of blocks. You can remove the block at the top quite easily. But if you have to remove the block at the end of the pile, you have to remove all the other blocks as well. Elements in Stack can be inserted or deleted only from one side. The insertion of an element into a stack is called push operation and the deletion of an element from the stack is called the pop operation. - Queue is a first in first out (fifo) linear data structure. Elements in Queue can only be inserted and deleted from opposite sides. The insertion of an element in Queue is called as en queue operation and the deletion of an element is referred to as a dequeue operation. What is a LinkedList? A linked list is a linear data structure where each element is a separate object. Linked list elements are not stored at a contiguous location; the elements are linked using pointers. Each node of a list is made up of two items - the data and a reference to the next node. The last node has a reference to null. The entry point into a linked list is called the head of the list. It should be noted that the head is not a separate node, but a reference to the first node. If the list is empty then the head is a null reference. What is Data Structure and Algorithms? Data Structure can be referred to as a collection of data objects that allows storing, organizing, and retrieving data on systems. An algorithm refers to a set of steps used in completing a certain task or to get the desired output. A deep understanding of Data Structures and algorithms helps in efficient and well-optimised coding. Data Structures and Algorithms are important since they are often considered to be the root or the foundation of computer science. They play an important role in implementing software and at the same time in the job interview process as well. ---------------------------------------- About SCALER -------------------------------------------------- A transformative tech school, creating talent with impeccable skills.
