Grammarly Coding Interview Questions

As a common Grammarly interview task, this question asks you to implement a robust algorithm for computing the factorial of a given non-negative integer. The challenge emphasizes proper input validation and the capacity to accurately process extremely large numeric results without overflowing standard data types. It is a great test of foundational programming and arithmetic handling. View the complete problem breakdown and optimal code solution by subscribing.

Presented in a Grammarly coding assessment, this puzzle focuses on manipulating text sequences using sliding window techniques and custom deduplication rules. You are asked to process a string and an integer parameter to filter out redundant characters within designated segments while preserving the overall processing order. The challenge tests your command over array manipulation, sliding window algorithms, and boundary condition handling in string transformations. To access the complete instructions, test examples, and official solution, a subscription is required.

This Grammarly interview question challenges you to build a word correction utility that compares a collection of target terms against a reference lexicon. The algorithm must evaluate exact matches, handle case normalization, and apply vowel interchangeability rules to identify the closest valid alternative. Testing your string manipulation and dictionary lookup abilities, this task requires efficient search strategies.

Master string manipulation techniques with this classic interview question shared by candidates interviewing at Grammarly. The exercise challenges you to examine a text sequence sequentially and eliminate neighboring duplicate character pairs until no adjacent matches remain. This tests your proficiency with linear data structures, specifically evaluating how effectively you can manage state changes during traversals.

Duplicate 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.
