The first question is two find the largest and second largest value at each level of a binary tree. You don't need to return all values, just print out instead. the second question is to return a value in an array with the probability proportional to the weight of the value within the array. For example, in an array [4,5,6], return 4 with probability 4/15, 5 with 5/15 and 6 with 6/15. You are given a function that returns a random real number between 0 and 1
Given an input array like [1,2,3] and a target like 5, find all combinations of array that sum up to target. [2,3] and [3,2] counts for only 1 combination.
Basic Networking and scripting ...It was not challenging but some of the questions were irrelevant to Job role or my expertise
Write a function that finds the square root of a decimal number.
Given an integer, return all sequences of numbers that sum to it. (Example: 3 -> (1, 2), (2, 1), (1, 1, 1))
"Reverse" of the problem if finding k-th smallest element in a tree: I had to find k-th largest.
Given the root of a binary tree and an integer targetSum, return all root-to-leaf paths where each path's sum equals targetSum.
Complete a function that returns a list containing mismatched words in two strings. The return list can be in any order. I used set to solve this question, but was also asked to verbally explain how I would solve it without using sets.
In most cases you need to have some experience with CUDA. If you want to increase your chances of getting a job offer you need to know very well about linked lists. We used the collabedit.com for the interview. It is like a chat but for coding. I got the following question on the screen of collabedit: // There is a chunk of memory in the kernel address space represented by kernelResource and an API exists to clear it. An IOCTL path exists to take a request from user-mode and using O/S services eventually dispatches to API_ZeroResource. From a security perspective what concerns do you have with this implementation? How would you fix them? // // KERNEL // BYTE kernelResource[10] = {0}; int API_ZeroResource( in_params *pParams ) { if (pParams->offset + pParams->length > sizeof(kernelResource)) return ERR_INVALID_LIMIT; memset(kernelResource + pParams->offset, 0, pParams->length); return 0; } // // USER // void ZeroResource() { in_params params = { ??? }; // an ioctl path exists to call API_ZeroResource ioctl( CMD_ZeroResource, ¶ms ); }
Question 2: What are the top five (ranked in decreasing order) single-channel media types that correspond to the most money the grocery chain had spent on its promotional campaigns?
