Amazon Coding Question - Insert Delete GetRandom O(1)

[@rohitvishwakarma1238]

I have been following different youtube videos for my leetcode help and I must admit your's explanation is the best!! Your explanation for any problem is so clear and concise. The animation, the easy to understand code, the way you take example test case and go through its every part without skipping any. Time and space complexity explanation. Everything is so perfect. Thank you so much! Keep up the good work :)

It is my pleasure, I'm glad it is helpful!

You have an amazing explanation man! Saw this question on a mock interview and was wondering how it would be solved in Java, as I didn't know whether you could use an ArrayList. Turns out you explained it perfectly in this video! Thanks!

[@juliahuanlingtong6757]

The overriding is pretty neat. I thought swaping with last element as first, but overriding is even better! Thumbs up

Awesome, thanks for watching!

Why we need to replace the value that will be removed with the last value in the array? Let's say our array is [1,2,3,4,5]. We want to remove 3. The resulted array will be [1,2,5,4,5]?

[@AlgosWithMichael]

Because removing from the end of an array list is O(1) which is a requirement for our delete function

[@krishnapidatala4127]

Excellent explanation. Why don't you make a course on Udemy? We are missing any course with this level of detail.

[@AlgosWithMichael]

Thank you! And I have thought about doing some super in-depth courses, but it would just depend on what everyone wants. Glad to hear you are in support of it!
