Suppose we have a polynomial f(x) with real coefficients {a0,a1,...,an}of degree n unknown, we could input x and get the output f(x). 1. What is the minimum trials of input to get all coefficients? 2. What if all coefficients are integers? 3. What is all coefficients are positive integers?
I was asked how I would estimate price of stock using history of its price.
Questions are almost exclusively quizzes, brain teasers, some logic, some (fewer than expected) about programming or real science/research, no real opportunity to talk about the daily work/atmosphere etc. Always slightly pushy.
