Quick Sort

This video explains the quick sort algorithm which is used to get elements of an array sorted. This is one of the most optimal of all sorting algorithms. We can sort an array in increasing, decreasing, non-decreasing and non-increasing orders. This video is from an interview dose live session. The quick sort algorithm depends on the input's nature and hence has the best-case and worst-case time complexity of O(NlogN) and O(N^2). This problem is similar to the sort colors problem which is also known as the Dutch National Flag problem. Quick sort involves choosing a pivot element and then placing it at it's correct position and recursively solving the left and right partitions. ======================================PLEASE DONATE============================= 🧡 SUPPORT OUR WORK: https://www.patreon.com/techdose 💚 UPI-ID: surya.kahar@ybl 💞JOIN Membership: https://www.youtube.com/channel/UCnxhETjJtTPs37hOZ7vQ88g/join ============================================================================== INSTAGRAM : https://www.instagram.com/surya.pratap.k/ LinkedIn: https://www.linkedin.com/in/surya-pratap-kahar-47bb01168 WEBSITE: https://techdose.co.in/ TELEGRAM Channel LINK: https://t.me/codewithTECHDOSE TELEGRAM Group LINK: https://t.me/joinchat/SRVOIxWR4sRIVv5eEGI4aQ ======================================================================= USEFUL LINKS: 🟠Must do TIPS to ACE Virtual Interview: https://youtu.be/4vLXoTFBB54 🟢Best strategy to excel your coding interview: https://youtu.be/NCQQGoHnx9U 🟡Get your dream job in 1 month: https://youtu.be/g_qAXBFglj0 🔵How to crack dream job in just 2 months: https://youtu.be/gX8ZapEkpUY 🟣7 Days DSA plan: https://techdose.co.in/7-days-dsa-cheat-sheet-quick-preparation-plan/
