16. Rotate Image
Rotate an n×n matrix 90 degrees clockwise in-place. Adobe is a graphics and imaging company — in-place 2D array transformations are a core competency that appears directly in image rotation, canvas transforms, and pixel buffer manipulation across Photoshop, Lightroom, and Illustrator.

17. Spiral Matrix
Return all elements of an m×n matrix in spiral order. Adobe's heavy focus on 2D array manipulation and image-buffer traversal makes this a recurring interview problem — spiral traversal is a canonical test of boundary-shrinking logic for pixel scan patterns.

19. Merge Intervals
Given a collection of intervals, merge all overlapping intervals. Adobe uses interval merging extensively in creative applications — timeline editing in Premiere Pro, selection ranges in Photoshop, and layer time spans all require efficient overlap detection and merging.

21. Word Search
Determine if a word exists in an m×n character grid where letters must be adjacent horizontally or vertically. Adobe uses this as a signature 2D DFS/backtracking problem — the grid-search pattern is directly applicable to font glyph shape recognition, texture atlas lookups, and region-growing algorithms in image segmentation.

23. Validate Binary Search Tree
Determine if a binary tree is a valid BST. Adobe asks this to test whether candidates understand the global invariant (not just local parent-child comparisons) — a level of rigor that mirrors validating hierarchical constraint systems in document structure and layout engines.
