    Quick Recall: Binary Search Worst-Case

    Quick Recall: Worst-Case

    Concept Formula / Rule
    Recurrence Relation
    Exact Max Comparisons
    Found vs Not Found Worst-case depth is identical.
    Comparisons per Step Check if 1 (3-way) or 2 (if-else).

    Halve the size, add one step,
    take the floor of the log, and never forget the plus one.

    Quick Recall: Preconditions & Representation

    Quick Recall: Preconditions

    Requirement Reason Consequence if Missing
    Sorted Order Enables elimination principle. Cannot discard half
    Random Access Enables mid calculation. Cannot jump to mid collapse
    Contiguous Memory Arrays provide direct indexing. Linked lists require traversal

    Sorting allows elimination. Contiguous memory allows instant jumps. You need both for .

    Most platforms hand everyone the same content. Here the content moves with your performance, topic by topic.

    Built around you, not around a syllabus PDF

    Every answer you give moves your topic-level intelligence rate. The next question, the next revision card and tomorrow's plan all change with it.

    Revision that hits your weak spots

    We only revise topics you have actually attempted and are still below the safe bar on — never the same chapter on repeat.

    Questions calibrated to the real exam

    Each question carries a measured toughness. You are served a rung above your current level, so practice keeps stretching you.

    Notes written for recall, not for volume

    Full lesson cards for first study, curated short-note cards for the last mile — with derivations, traps and exam patterns marked.
