Round 1: Coding interview - You are given an array of integers nums, there is a sliding window of size k which is moving from the very left of the array to the very right. You can only see the k numbers in the window. Each time the sliding window moves right by one position. Return the max sliding window. Example 1: Input: nums = [1,3,-1,-3,5,3,6,7], k = 3 Output: [3,3,5,5,6,7] Explanation: Window position Max --------------- ----- [1 3 -1] -3 5 3 6 7 3 [-1, 1, 3] 1 [3 -1 -3] 5 3 6 7 3 [-3, -1, 3] 1 3 [-1 -3 5] 3 6 7 5 [5] 1 3 -1 [-3 5 3] 6 7 5 [3,5] 1 3 -1 -3 [5 3 6] 7 6 [] 1 3 -1 -3 5 [3 6 7] 7 Example 2: Input: nums = [1], k = 1 Output: [1] - Given a string s containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid. An input string is valid if: Open brackets must be closed by the same type of brackets. Open brackets must be closed in the correct order. Example 1: Input: s = "()" Output: true Example 2: Input: s = "()[]{}" Output: true Example 3: Input: s = "(]" Output: false Input: s = "[{()}]" Output: false Round 2: Projects explanation - Explain the current project architecture - Distributed transaction management in orchestration design pattern - How to handle distributed transactions when the orchestrator died during the processing.
