Stacks : Basic, STL and Implementation | Lecture 54 | Java and DSA Course

In this video, Raghav Sir will teach you Basics of Stack Data Structure. This is Lecture 54 of the JAVA & DSA series and the first video of Stack. STL / Collection Framework is covered along with a lot of basic questions and most importantly the implementation of Stack via array and linked list both are covered. Interview questions of Stacks will be covered in the next Lecture in detail, coming VERY SOON. 00:00 Introduction 04:00 What is a Stack 10:15 Stack in Collection Framework / STL 28:13 Comparing Arrays, Lists and Stacks 32:56 Q1 : Copy stack into another in same order 45:37 Q2 : Push at bottom / any index - iterative 1:03:13 Q3 : Display and reverse display stack recursively 1:24:48 HW 4 : Pop from bottom / any index 1:27:13 Q5 : Reverse the given stack - Iterative 1:32:05 Q6 : Reverse the given stack - Recursive 1:45:29 Stack Underflow 1:50:02 Stack Overflow 1:52:42 Array implementation of Stack 2:20:28 Linked List implementation of Stack 2:43:09 Advantages of Array Implementation 2:47:15 Advantages of Linked List Implementation 2:49:29 Summary 2:51:14 Maza aa gaya Annotated Notes : https://drive.google.com/drive/folder...
