One Pager Cheat Sheet

  • You can merge multiple sorted linked lists into a single sorted linked list, with time complexity of O(n*k*log k) and space complexity of O(k).
  • We can improve the brute force solution to sorting a list of linked lists by introducing a Priority Queue data structure, which allows us to efficiently process and order elements one by one in O(n log n) time.
  • The process involves running the linked lists through the designated software to achieve the desired result.
  • Always check for an empty array before attempting any operations.
  • Putting it all together is the key to achieving success.

This is our final solution.
