This pull request introduces new implementations for data structures and algorithms, specifically a Segment Tree and Dijkstra's Algorithm, along with their respective unit tests. The most important changes include the addition of the
SegmentTreeclass, thedijkstrafunction, and their corresponding tests.New Implementations:
src/data_structure/segment_tree.hpp: Added theSegmentTreeclass with methods for building the tree, querying intervals, and updating elements.src/graph/dijkstra.hpp: Added thedijkstrafunction to compute the shortest paths from a single source in a weighted graph using Dijkstra's Algorithm.Unit Tests:
tests/data_structure/segment_tree_test.cpp: Added unit tests for theSegmentTreeclass, including tests for sum and minimum operations.tests/graph/dijkstra_test.cpp: Added unit tests for thedijkstrafunction, including tests for small graphs and graphs with disconnected nodes.
