In this coding interview tutorial for Python, Caelan solves a problem from LeetCode in 3 different ways⁠— each one more sophisticated than the last. Iterating on your solution in a technical interview is an important skill as it's unlikely that you'll land on the perfect performance solution on your first attempt.

we can also use linkedlist for constant intertion and do the binary search on linkedlist

This went a little fast; I had to pause at times when multiple lines magically materialized, but this was just the thing I want more of. No heavy accent, runs through the O(), shows several ways to get the same answer and shows all the code in PYTHON. Can we please have a series of 100+ videos like this, categorized by type of solution? Luv ya.

Been doing some testing with the lvl3 code and I don't think it works the way you think it works.
For example, just by adding: med.addNum(13) and trying to execute the med.findMedian() it returns 6.5 which is incorrect (We should expect 6 here)

From what I could tell, when adding the 13 the code sees that the self.low is smaller than self.high and them proceeds to take the smallest_high from self.high (6) and put in in the self.low

In the findMedian func bc the self.low is greater the self.high it then skips to the else statement and tries to do the calculations as if the numbers provided were even
