Keep making them videos bro! Thank you!

[@steverogers9453]

You're amazing!! Keep up the good work. This helps a lot. Thanks

[@xavierelon]

Thank you!

[@borlorbao]

Cheers for the video, I finally understand this

[@devdev19]

Good solution. Hope you keep uploading

[@codingcat1836]

Hey Xavier, great explanation! May I know the app you used to project iPad whiteboard to the Mac? It's much easier on my neck to look at sketches on the screen instead of the iPad. Thanks!

[@xavierelon]

Hey Kester, it’s QuickTime on my MacBook. I just cast it

[@codingcat1836]

@@xavierelon Oh, so you casted a prerecorded video to iPad with a notebook open to record? Kinda counter-intuitive lol

[@xavierelon]

@@codingcat1836 what? No I was drawing live. I plug it in and it mirrors my iPad

[@codingcat1836]

@@xavierelon Oh are you referring the sidecar functionality? How did you pull off recording both Mac and iPad screen then, just curious. Thanks!

[@cosmoatlas2435]

Great content! you can also use a min heap to maintain the order of the Ugly numbers instead of using Math.min method.

[@xavierelon]

That’s a great point. I did not think of that. Thank you

[@saunaknandi1814]

use for loop upto n only why to iterate upto 1675

You know, this code was as simple as it gets and most of us get it that it WORKS. The idea should be to explain the intuition behind it/ why does it work? Thanks!

[@xavierelon]

Sorry my explanation was not sufficient. I tried to cover the minimum 2,3,5 factors as best as I could explain in my head

[@duedares]

@@xavierelon That's cool mate. Totally appreciate the effort 🎈

[@mr.mystiks9968]

I agree. Once you’re in the interview, you can’t gamble on getting asked a question you’ve solved previously. There is a thought process on how to break down the problem, make some observations, and lean towards an intuition. No use in watching you code tbh.

Remove your photo from the code!

[@xavierelon]

Sorry about that
