How do you find the biggest number ?

4 respostas

Sort and use binary search.

If you sorted the list of numbers why would you have to binary search to pick it out? It should either be the first or last one in the list depending on what you past as your comparator. And sorting is slow for this kind of question, since you will be removing and inserting items to figure out which one is the biggest. What they probably wanted to hear is if they didn't want it optimized was a single for-loop with a comparator. This should get done in O(n). If they wanted it optimized, a divide and conquer strategy will find the answer in lesser number of comparisons. If you're looking for a STD solution it's "std::minmax_element(first, last);" Menos

You are so right ! Now I can't remember whether the question was to find a target number, or the biggest. If the latter, then for sure that would be the killer reason I failed the interview! Thanks very much for the solution. Menos

Isn’t it true that you should pass 3/3?

They gave me the same test on HackerRank which I did successfully (it passed all test cases). Yet my candidacy was rejected. I used a map container. I couldn't find any container suitable for the job. There may be a better solution which I am was not able to figure out. After reading this post, I am also feeling that they are biased :( Menos

I'm curious about the "racially charged" - that's pretty bad. Since you mentioned 20 years it could be more a case of age discrimination (rampant in IT unfortunately) than racial bias. Menos

Sequence of numbers in random order and 1 of them is missing how to find that out...

4 respostas

If the sequence is guaranteed to contain only positive integers, it can be done like so: Read in the sequence, noting the MIN and MAX numbers. The sum IF it started from 1 would be MAX(MAX-1)/2. The sum of the 'missing' numbers (from 1 up to where the sequence actually starts) is (MIN-1)*MIN/2. The missing number is given by taking the difference between the two: X = [MAX*(MAX-1) - (MIN-1)*MIN]/2. Menos

Oops, in addition to what I put above there is a final step to get the actual answer. The missing number is equal to X minus the sum of the numbers given. Menos

N(N+1)/2 - sum of the input = missing number

Most of the questions were of the "Tell me about a time when you had to..." variety (STAR: Situation, Task, Action, Result). You also are given a folder at the beginning and you have to choose 3 words, out of 9 possible, that best describe you, and you are asked to explain why you chose each one of them. Another question was why am I interested in the insurance industry? (Answer I gave below).

3 respostas

I chose the insurance industry because it is one of the most stable industries and offer opportunities for growth. Menos

If you need help passing the CCAT (hardest part of the process in my opinon) I passed it by studying ruthlessly. I found this site that has the same CCAT as crossovers and just took that a bunch of times. crossoverccat[DOT]com I recommend this for anyone that has the proctored CCAT coming up. The salary is $15 / hr which is really good in my country. 40 hours a week min/max. Menos

Given an array of integers of size N, and an int L, find if L is in N. Then they ask how many "=" are in this solution. Then they ask you to cut it by about half.

3 respostas

***First solution will be*** go over the whole array in a loop and put an if statement calling if the arr[i] == L. inside the if we call L is in the array outside the loop, we call L is not in the array this sol has 2 "=" ***second solution will be *** firstly we need to sort the array and then using a loop we again use if statement the statement checks if L is smaller the arr[i] if it is true so we know L is in the array at the end of the loop, we declare L is not in the array Menos

+ + int the second answer I needed to check if the equals or smaller + + then the second solution is evolving 1 "=" Menos

"if it is true so we know L is in the array" - why? if the array is [2,3,5] and L = 1, you will return true because L <= arr[0] Menos
