const responseToTimeseries = (response) => {
  // your implementation goes here
  
  // find the earliest and latest timestamp in the time series.
  // assuming any time point can be missing from the input, even the earliest one.
  let earliest = Infinity, latest = 0;

Practice Exam Attempt (3) Carefully taken with notes

Got an 16/20 on the latest practice exam. Missed questions 5, 7, 12, 13.

Summary of why missed each question:

5

always favor simpler method (cbt (cloud big query tool) vs hbase cli) … I feel uneasy with this answer

7

prefer simpler method. pub/sub more than capable. kafka is overkill. this question showed my lack of knowledge of pub/sub capabilities
