Pull request overview
This PR adds solutions to LeetCode problem 1059 "All Paths from Source Lead to Destination", implementing a DFS-based algorithm with cycle detection to verify if all paths from a source node lead to a specific destination node in a directed graph.
- Implements DFS with state tracking (0=unvisited, 1=visiting, 2=visited and valid) to detect cycles
- Adds solutions in 5 programming languages: Python, Java, C++, Go, and TypeScript
- Includes comprehensive documentation with problem description, examples, constraints, and solution explanation
