Literally the best DSA course I've ever watched, I always struggled to learn about DSA since I'm more of a developer than a DSA lover and never enjoyed all this but this course changed my mindset and really helped me a build a foundation for it. Moreover, the teaching style of the instructor is just awesome. Thanks a ton Piyush! :)
