- SalesforceMediumMember of Technical StaffConvert a Sorted Doubly Linked List to a Balanced BST In Place
Tests in-place pointer manipulation and bottom-up tree construction by converting a sorted doubly linked list into a height-balanced binary search tree in linear time.

Design a resilient payment platform that guarantees zero duplicate charges and safely resolves ambiguous downstream gateway timeouts.
System DesignOnsiteDistributed SystemsPaymentsIdempotency - SalesforceMediumMember of Technical StaffExplain the Recursion Tree of Merge Sort
Explain the merge sort recursion tree from a five-element example through the general recurrence. Derive per-level work, uneven split height, Theta(n log n) time, merge-buffer space, call-stack depth, stability, and empty-input handling.
Software Engineering FundamentalsOnsite - SalesforceMediumMember of Technical StaffImplement Merge Sort and Return a Sorted Array
Tests your ability to implement a classic divide-and-conquer merge sort algorithm from scratch, maintaining stability and achieving O(n log n) time complexity without relying on built-in sorting utilities.
