Deep Copy a Singly Linked List
3/5Duplicate a singly linked list so that the copy shares no node with the original and neither can be changed through the other. This Grammarly question is short but specific: every node must be newly allocated and the link structure must match exactly. You will build the copy in one pass with a trailing pointer, handle the empty list, and explain how the approach would change if nodes carried extra references. A subscription unlocks the complete problem and the reference solution.
Coding & Leetcode-style QuestionsGrammarlyCopy an Image Matrix
2/5This Luma AI interview question asks you to implement a memory-safe deep copy operation for a two-dimensional grid representing a grayscale digital image. You will parse raw dimensions and pixel values from standard input, construct an independent replica of the matrix, and output the duplicated grid without relying on external utility libraries. This task examines your foundational grasp of multi-dimensional array manipulation and memory allocation in programming.
