The14subdistrict management platform adopts a role‑based architecture, splitting functionality between administrators and residents. The system is built around the Spring Boot framwork and follows the MVC pattern, with a MySQL database providing back‑end storage and Vue.js powering the front‑end use...
Negative Cycle DetectionWhen detecting negative cycles reachable from a starting node, two primary algorithms are used: Bellman-Ford and SPFA (Shortest Path Faster Algorithm).In the Bellman-Ford algorithm, shortest paths are computed over n-1 iterations. If a relaxation is still possible during the...
Linked List Variants Singly linked lists contain nodes with a single pointer to the next node. Doubly linked lists include two pointers per node: one to the next node and one to the previous node, enabling bidirectional traversal. Circular linked lists form a closed loop where the last node points b...

The curlify library enables conversion of Python requests objects into executable cURL command strings. This functionality is particularly useful for debugging HTTP intercations and replicating API calls out side of Python environments. Installation is performed via pip: pip install curlify Once ins...
Copy List with Random Pointer This problem is a classic deep copy scenario, similar to graph cloning (e.g., LeetCode 133). Approach: Traverse the list once to copy the next pointers. During this traversal, store the mapping between original nodes and their copies in a hash map. Traverse the list a s...
Perceptrons: The Building Blocks Introduced by Frank Rosenblatt in 1957, the perceptron is a fundamental unit of artificial neural networks. It takes multiple input values, multiplies each by a corresponding weight, sums these weighted inputs, and then applies an activation function to produce an ou...
