DSA-Lite for Screens

What this topic will cover

• An easy array/string set — reverse words, remove duplicates, anagram check, hand-written in C.
• A recap of the linked-list drills from 1.7.B — reverse, middle, cycle detection, re-verified cold.
• Stack and queue implemented over a plain array.
• Bubble/insertion sort by hand, plus qsort with a comparator (the payoff of 1.7.A), a handwritten off-by-one-proof binary search, and the O(1)/O(n)/O(log n)/O(n²) talk-track for all of it.
