This problem tests arbitrary-base conversion where the number is stored as a linked list. The core idea is to extract the base-10 value, then repeatedly apply modulo and division to build the new-base list. It evaluates understanding of linked-list big-integer representation and digit extraction logic. The VOprep team has long accompanied candidates through various major company OAs…

There are 2 single linked list, one is ascending sorted, the other is descending sorted, write code to merge them together, result in ascending sorted. For example:L1: 1->2->3L2: 6->5->4 Result:1->2->3->4->5->6 Requirements:Time complexity: O(M + N), M is the length of L1, and N is the length of L2Space complexity: O(1) Please write code to solve…

Problem 1 Imagine you’re working on a language which only support Stack, but you need a Queue functionality to fulfill the requirement. Problem 2 Given:const a = 1;const b = ‘1’;What is the result of each of the following statements: a == ba === b!a === !ba + ba + +b These are typical Microsoft…

Recently, Microsoft interview activity has noticeably increased again. One thing that has always been true about Microsoft is that interview content heavily depends on the team — different teams test very different skills. This time, all three of my rounds followed the pattern of resume deep-dive + coding questions, with no system design and no…

Problem statement（题目原文）Given: What is the result of each of the following statements? Brief idea Know == performs coercion (string → number), === doesn’t; + concatenates when a string is involved; unary + coerces to number.
