Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. The number of elements initialized in nums1 and nums2 are m and n respectively. You may assume that nums1 has a size equal to m + n such that it has enough space to hold additional elements from nums2.

You are given an array of k linked-lists, each sorted in ascending order. Merge all the linked-lists into one sorted linked-list and return it.

Explain the fundamental differences between stack memory and heap memory, including how memory is allocated and deallocated in each, their typical use cases, and their performance characteristics.

Discuss the advantages of using std::vector in C++ compared to raw arrays or other dynamic data structures like std::list. Consider aspects such as memory management, performance, and ease of use.

Compare the traversal efficiency of linked lists versus arrays. Explain the underlying memory access patterns and how they affect performance for sequential and random access. Discuss scenarios where one data structure would be preferred over the other for traversal.

Given a string s and an integer k, return the length of the longest substring of s that contains at most k distinct characters.

Design and implement a Least Recently Used (LRU) cache. It should support the following operations: get and put. get(key) will retrieve the value of the key if it exists in the cache, otherwise return -1. put(key, value) will insert the key-value pair or update the value if the key already exists. When the cache reaches its capacity, it should invalidate the least recently used item before inserting a new item.

Explain the concepts of vertical scaling (scaling up) and horizontal scaling (scaling out) in system design. Discuss their advantages, disadvantages, appropriate use cases, and limitations.

Describe how you would architect or implement measures to prevent or mitigate a Distributed Denial of Service (DDoS) attack from significantly impacting your software or system. Discuss various layers of defense.

Discuss key concepts in system design including Microservices architecture, Load Balancing techniques, and Master-Slave architecture for databases. Explain their purposes, benefits, drawbacks, and how they contribute to a robust and scalable system.
