A dataset which contains examples labeled with different classes• (single label, multiple classes), for example an animal image classification dataset containing different types of animals, one animal per image. You want to randomly sample an n-element subset from this dataset in such a way that the classes are as balanced as possible (least difference between the number of examples sampled from each class). Write a function which given n and the number of examples in each class, computes how many examples should be sampled from each class.

medium/hard algorithms questions, 3 questions, had to at least solve 2 of them and the 3rd if you had time it seemed. Architectural was based on a system they already had, pretty interesting to build out with the interviewer

Given a set of events [e1, e2, e3, ... , eN] occuring at given times and a set of timeframes [t1, t2, .., tM] each having a start timestamp and an end timestamp, give an algorithm for each event the number of timeframes it occurs within (white board, no code)
