An Initial CodeSignal Assessment Assignment.
After a lot of personal questions about myself, educations and work experieces, a tecnical problem about... "I have a bunch of numbers, find the best and optimized solutions to eliminate one digit only to, overall, get the lowest number"
Algorithm Question: Is the number range "saturated". I put the word saturated in quotes, because their definition is somewhat ambiguous, after prodding the interviewers, the number range can be fully saturated, over-saturated in certain ranges or under-saturated. Input is a list of arraylist of 2 integers (each pair represents a range) Input 1: [2,5 | 0,2 | 10,15 | 6,9] Output: Saturated (logically this is over saturated because number 2 occurs twice but not according to the interviewers, creating additional edge cases for your algorithm) Output for the above is, yes the range is "perfectly" saturated because it accounts for all numbers from 0-15. Trick: interviewers consider even though the number 2, which occurs twice to be ok and not over saturated. Input 2: [3,10 | 0,5 | 50,100] Output: "not saturated" ("over saturated", the overlap is more than one number) Note for above range, it is both over saturated and under saturated, but interviewers don't mention/care about this Input 3: [5,9 | 0,3] Output: not saturated
Behavioral: Past experience, difficult situations, learning from mistakes, missing deadlines etc. Typical behavioral and hr stuff.
Given two arrays: arr1[0..m-1] and arr2[0..n-1]. Find whether arr2[] is a subset of arr1[] or not. Both the arrays are not in sorted order. It may be assumed that elements in both array are distinct.
