+# Class ArticulationPoint
+
+Given a graph generated using GraphBuilder.makeGraph(), this class finds all articulation points in graph. Since GraphBuilder assumes 0-based indexing, this class also works assuming 0-based indexing.
+
+All members of this class are static, so no constructor defined.
+
+## Methods
+
+### articulationPoints
+```
+public static boolean[] articulationPoints(int[][] graph)
+```
+Returns boolean array of length $N$ where $N$ denotes the number of nodes in given graph, i-th element in this boolean array denotes whether i-th node in given graph is an articulation point or not.
+
+** Constraints **
+* graph is generated using GraphBuilder.makeGraph(), so all constraints applicable to makeGraph method applies.
+
+** Computational complexity **
+* $ O (NumberOfNodes + NumberOfEdges) $
