Another was a puzzle: A king orders 100 bottles of wine for a celebration. A courtier who's angry with the king over something puts poison in one of those bottles. The king has a way of identifying the poisoned bottle by giving a few drops of wine to a monkey. Since the poison is fast acting, the monkey will die immediately. Whats the minimum number of monkeys needed to find the poisoned bottle?

Question Description: Write a function that, given a list of integers (both positive and negative) returns the sum of the contiguous subsequence with maximum sum. Thus, given the sequence (1, 2, -4, 1, 3, -2, 3, -1) it should return 5.

Write a program that given 4 coin denominations and a dollar amount finds the best way to express that amount using the coins given. I.e. you have coins with denominations of 1c, 7c, 13c,19c and you have to express $2.12 with the least number of coins. There is always a 1c coin but the other 3 are arbitrary.

Behavioral Why outreach The impact you hope to have from your next role?What is most important factor in your career/job What do you think about RSpec? How do you compare it with other frameworks What was the hardest/Challenging technical problem you faced and how did you resolve it Coding This problem concerns finding a time when we can do daily recurring maintenance on a server. You are to write a function that is given the following information: List of times when the server is busy every day Duration, in minutes, of the desired maintenance window The function should return the start time of a daily maintenance window when the server is not busy. In pseudo-code, the function signature would look something like this: maintWindowStart(busyTimes, durationMins) -> startTime The "busy times" should be time ranges like the following, and can be represented in whatever data structure you feel is appropriate. 0:05 to 0:30 = [5, 30] 2:00 to 4:01 = [120, 241] 13:10 to 16:55 = [790, 1015] [[5, 30], [120, 541], [790, 1015]] // requested duration -> expected start time // 10 -> 30 // 120 -> 541 // 4 -> 0 // 300 -> 1015
