Asexual reproduction requires fertilization of an egg by a sperm.

Consider the Graph class stub in C# given below, which was used in Lab 2. As the producer of the Graph class, write a method which accepts an array of integers as input, and determines whether the elements of the array form a cycle (ordered by array index). class Graph {         private object[] vertices;         private bool[,] edges;           public Graph(int numVertices)         {   …   }         public int getNumVertices()         {   …   }         public void addVertexData(int vertexNumber, object vertexData)         {   …   }         public void addEdge(int vertex1, int vertex2)         {   …   }         public void removeEdge(int vertex1, int vertex2)         {   …   }         public bool hasEdge(int vertex1, int vertex2)         {   …   }         public object getVertexData(int vertexNumber)         {   …   }         public bool isConnected()         {   …   }         public bool hasCycle()         {   …   }         public bool isTree()         {   …   }                  private int[] depthFirstSearch(int s)         {   …   }         //more private methods below     }  

Suppose that A and B are two algorithms that perform the same task, t. Also suppose that the worst-case time-complexity of A is and the worst-case time-complexity of B is . Is this enough to decide which algorithm you would use? Is there any possibility that B could be faster than A? Explain.
