In this video Raghav sir will introduce you to the world of circular queues and show you how to implement them in Java using arrays and linked lists. Our instructor will guide you through the ins and outs of circular queues, including their advantages and how they differ from regular queues. But that's not all - we'll also explore the exciting world of deques! You'll learn about the deque interface in Java collections, its member functions, and how to use them to solve common programming challenges. So join us in mastering the art of circular queues and deques and take your DSA preparation to the next level! 00:00 - Introduction 02:05 - Today’s checklist 02:08 - Q1 : Reverse first k elements of a queue 12:05 - Q2 : Implement stack using queues 32:23 - Q2 : Pop efficient approach 41:32 - Q3 : Implement queue using stacks 53:06 : Q4 : First negative in each window of size ‘k’ 1:24:38 : Q5 : Reorder queue 1:58:37 : next class flow 1:59:37 : Thank you !! 1) Data science Masters 2.0 Hinglish batch : https://pwskills.com/course/Data-Science-masters-2.0?source=course_listing_page English batch : https://pwskills.com/course/Data-Science-Masters-2.0?source=course_listing_page 2) Full Stack Web Development 2.0 Hinglish batch: https://pwskills.com/course/Full-Stack-web-development-2.0?source=course_listing_page English batch: https://pwskills.com/course/Full-Stack-Web-Development-2.0?source=course_listing_page 3) Java with DSA and System Design 2.0 Hinglish batch: https://pwskills.com/course/Java-with-DSA-and-system-design-2.0?source=course_listing_page English batch: https://pwskills.com/course/Java-with-DSA-and-System-Design-2.0?source=course_listing_page 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 📌 For any queries or complaints Visit : https://bit.ly/PW_Queries #Queues #InterviewQuestions #Leetcode #Java #DSACourse #CollegeWallah #PWSkills #PhysicsWallah
