Previous Smaller Element | Previous Greater Element

In this video, we solve two stack problems: "Previous Smaller Element" and "Previous Greater Element." We also discuss similar problems you can solve, like "Next Greater Element" and "Next Smaller Element." Time Complexity: O(n) as each element is pushed and popped from the stack at most once. Space Complexity: O(n) for the stack used to store elements. Stay tuned for more tutorials as we continue our journey to help you crack job interviews with key data structures. ================================================= ✉️ Join our FREE Newsletter: https://vizuara.ai/our-newsletter/ ================================================= 🌟 Meet Our Team: 🌟 🎓 Dr. Raj Dandekar (MIT PhD, IIT Madras department topper) 🔗 LinkedIn: https://www.linkedin.com/in/raj-abhijit-dandekar-67a33118a/ 🎓 Dr. Rajat Dandekar (Purdue PhD, IIT Madras department gold medalist) 🔗 LinkedIn: https://www.linkedin.com/in/rajat-dandekar-901324b1/ 🎓 Dr. Sreedath Panat (MIT PhD, IIT Madras department gold medalist) 🔗 LinkedIn: https://www.linkedin.com/in/sreedath-panat-8a03b69a/ 🎓 Sahil Pocker (Machine Learning Engineer at Vizuara) 🔗 LinkedIn: https://www.linkedin.com/in/sahil-p-a7a30a8b/ 🎓 Abhijeet Singh (Software Developer at Vizuara, GSOC 24, SOB 23) 🔗 LinkedIn: https://www.linkedin.com/in/abhijeet-singh-9a1881192/ 🎓 Sourav Jana (Software Developer at Vizuara) 🔗 LinkedIn: https://www.linkedin.com/in/souravjana131/ ================================================= #python #datastructures #slidingwindow #programming #coding #learnpython #datastructureandalgorithms #ai #machinelearning
