ComiXology Thousands of Digital Comics.Round 1: After general introduction, the interviewer asked me if I was good with arrays. Answer : Sort the arrays. Calculate sum of both arrays and take out difference of the sum. If found — it is possible return 1else return 0.
Answer : This is how I told explained him the solution. If the difference was odd — it means it is not possible to make the sum same by swapping two elements. Interviewer asked me why the difference needs to be odd? I told him that any transaction resulting from swapping two elements will always result in even increments or deductions in the sum value. He was convinced and told me to continue. So yeah it will help if we also sort the arrays so then we can use binary search.
If a pair is found we return 1 else we return 0. He told me to write the code for the same and I did while simultaneously explaining some assumptions I was taking to avoid corner cases for now and conditions. He read the code and asked some doubts which I explained nicely and he was convinced. He asked what if the number of coins initially are odd. I told him that the game would be unfair then, but he said lets make it unfair, now how will you win? I told him that if the sum of odd elements now is greater than even ones then only I can win otherwise its not possible for me to win in this situation.
He countered with some examples but was convinced by the end. Problem 3 : Given a BST replace every node with sum of all nodes which are greater than that node. Answer : Pretty easy recursive approach. I struggled with two flawed solutions before presenting the third correct one. Round 2: Friendly and encouraging interviewer. He asked me two problems, one on Binary Tree and another on vector and maths.You will still need to enter the security code in addition to your password.
Two-Step Verification is a feature that adds an extra layer of security by asking you to enter a unique security code in addition to your password on computers and devices that you haven't designated as trusted. If you have Two-Step Verification enabled on your account, you will need to enter an additional code in order to register a device. If your device or app does not display a separate page for you to enter your unique security code when you attempt to register, you will receive an error message after you submit your password, even if the account password you entered was correct.
Note: You will not be able save a device as a trusted device if the Alternate Sign In is required. If you are required to register your device or application using a temporary passwordyou will need to first attempt to register with your temporary password, then receive your Two-Step Verification code, and then add your Two-Step Verification code to the end of the temporary password you receive.
