Java and DSA Foundation Course - 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/folders/1qkMaNVdJnvTsxfTZsakTsFcILlAYsL3K?usp=sharing For any Batch Related Queries Please Connect - 7019243492 Decode Batch:- DSA with C++ (Hinglish) http://bit.ly/4108YQC BINARY 2.0 Batch:- Java-with-DSA-&-System-Design 2.0(Java with DSA & System Design) https://bit.ly/3MfYusn (Hindi) http://bit.ly/40CvkrD (English) SIGMA 2.0 Batch:- Full-Stack-Web-Development 2.0(MERN Stack) http://bit.ly/3ZzShKJ - (Hindi) http://bit.ly/3zuBT3H - (English) IMPACT 2.0 Batch:- Data-Science-Masters 2.0(Full Stack Data Science) http://bit.ly/3U9EEAM (Hindi) http://bit.ly/3m2K5VR (English) Website - https://pwskills.com/ Instagram - https://www.instagram.com/pwcollegewallah/ Linked In - https://bit.ly/3ZFuBog Telegram - https://t.me/SkillsPW Discord - https://discord.gg/m7YSX6Xh Twitter - https://twitter.com/pw__skills 📌 𝐏𝐇𝐘𝐒𝐈𝐂𝐒 𝐖𝐀𝐋𝐋𝐀𝐇 𝐎𝐓𝐇𝐄𝐑 𝐘𝐎𝐔𝐓𝐔𝐁𝐄 𝐂𝐇𝐀𝐍𝐍𝐄𝐋𝐒 : 🌐 PhysicsWallah -Alakh Pandey: https://youtube.com/@PhysicsWallah 🌐 Alakh Pandey: https://youtube.com/@alakhpandey1414 🌐 JEE Wallah: https://youtube.com/@jee_wallah 🌐 Competition Wallah: https://youtube.com/@PW-NEETWallah 🌐 PW Foundation: https://youtube.com/c/PhysicsWallahFoundation 🌐 NCERT Wallah: https://www.youtube.com/channel/UC8zCnnfhz-dvIpVdZ1CheuA 🌐 Defence Wallah: https://youtube.com/channel/UC8OCoGX9tmMneOzIFUTWq2Q 🌐 PhysicsWallah English: https://youtube.com/@EnglishPW 🌐 PW Vidyapeeth: https://youtube.com/@VidyapeethPW 🌐 Commerce Wallah by PW: https://youtube.com/@commercewallahpw 🌐 CA Wallah bt PW: https://www.youtube.com/channel/UC2amkJX5zDyQJ0mDajAWRSA 🌐 PW Sarkari Exam: https://youtube.com/@PWSarkariExams 🌐 PW - Hindi Medium: https://youtube.com/@physicswallahhindimedium 🌐 PW Bangla: https://youtube.com/@pwbangla 🌐 PW Maharashtra: https://youtube.com/@PWMaharashtra 🌐 PW Telugu: https://youtube.com/@PWTelugu 🌐 PW Kannada: https://youtube.com/@PWKannada 🌐 PW Gujarati: https://youtube.com/@PWGujarati 🌐 PW Facts: https://youtube.com/@pwfacts 🌐 PW Insiders: https://youtube.com/channel/UCHMWQFr9Nwo3wJsAap2Wnfw 🌐 PW Little Champs: https://youtube.com/@pwlittlechamps 🌐 PW Pathshala: https://youtube.com/channel/UCcXUY9NSMyYbkOvUD97CUmA 🌐 Banking Wallah : https://www.youtube.com/channel/UCg5_K50hLTKerLkSE7I1yWQ 🌐 SSC Wallah : https://www.youtube.com/channel/UCcaEVV7A47J4k9GFcqOOYkg 🌐 JEE Challengers by PW : https://www.youtube.com/channel/UCyf71tWV2abeN-l_UKiJ-5g 🌐 UPSC Wallah : https://www.youtube.com/channel/UCqOy6oOu6RPJNHYQ8f_Ybvg 🌐 UPSC Wallah हिन्दी : https://www.youtube.com/channel/UCmrP-DYdZuThp8AO9lnnwNw 🌐 GATE Wallah : https://www.youtube.com/channel/UC9PoSJoftLvEnXT-PtQ5Wtw 🌐 GATE Wallah - EC,EE & CS : https://www.youtube.com/channel/UCuGWIkiNaWjsCqybgxGuxfg 🌐 GATE Wallah - ME, CE & XE : https://www.youtube.com/channel/UCGrrw9x3_B_fItUIBMvqAUw 🌐 GATE English : https://www.youtube.com/channel/UCOsV75fSUr8gnMbhx-Qh3Lg 🌐 College Wallah : https://www.youtube.com/channel/UCDrf0V4fcBr5FlCtKwvpfwA 🌐 PW IIT JAM & CSIR NET : https://www.youtube.com/channel/UCuj28Zll58sztDqLiDhzgtQ 🌐 Teaching Wallah: https://www.youtube.com/channel/UCUzqJZOkCejFoc5eqWWA9Eg 🌐 CUET Wallah: https://www.youtube.com/@cuetwallahpw 📌 𝐏𝐇𝐘𝐒𝐈𝐂𝐒 𝐖𝐀𝐋𝐋𝐀𝐇 𝐒𝐎𝐂𝐈𝐀𝐋 𝐌𝐄𝐃𝐈𝐀 𝐏𝐑𝐎𝐅𝐈𝐋𝐄𝐒 : 🌐 Telegram : https://t.me/Physics_Wallah_Official_Channel 🌐 Facebook : https://www.facebook.com/physicswallah 🌐 Instagram : https://www.instagram.com/physicswallah/?hl=en 🌐 Twitter : https://twitter.com/physics__wallah 📌 For any queries or complaints Visit : https://bit.ly/PW_Queries #Stacks #STL #Java #DSACourse #CollegeWallah #PWSkills #PhysicsWallah #JavaTutorial
