Lowest Common Ancestor of a Binary Tree

Data Structures & AlgorithmsMedium

Given a binary tree, find the lowest common ancestor (LCA) of two given nodes in the tree. According to the definition of LCA on Wikipedia: “The lowest common ancestor is defined between two nodes p and q as the lowest node in T that has both p and q as descendants (where we allow a node to be a descendant of itself). For example: If the tree is [3,5,1,6,2,0,8,null,null,7,4], p = 5, q = 1, then the expected output is 3, because the LCA of nodes 5 and 1 is 3. If the tree is [3,5,1,6,2,0,8,null,null,7,4], p = 5, q = 4, then the expected output is 5, because the LCA of nodes 5 and 4 is 5, since a node can be a descendant of itself according to the LCA definition. If the tree is [1,2], p = 1, q = 2, then the expected output is 1. Consider these constraints: The number of nodes in the tree is in the range [2, 10^5]. -10^9 <= Node.val <= 10^9 All Node.val are unique. p != q p and q will exist in the tree.

Describe the system design of your Salesforce integration with a Java backend.

System DesignMedium

Let's discuss the system design of your existing Salesforce integration with a Java backend. Could you please elaborate on the architecture, including specific details about data flow, integration patterns, and technologies used? For example, walk me through a scenario where a new account is created in Salesforce, and how that information propagates to your Java backend system. What mechanisms are in place for real-time updates versus batch processing? How do you handle data transformations and ensure data integrity across both systems? What are the key considerations for scalability, security, and fault tolerance in your design? Finally, describe the monitoring and alerting mechanisms you have implemented to ensure the integration is running smoothly and to quickly identify and address any issues that may arise. Provide details on the error handling strategies employed to prevent data loss or corruption in the event of failures.
