Given a directed graph, check whether the graph contains a cycle or not. Your function should return true if the given graph contains at least one cycle, else return false. Example, Input: n 4, e = 6 0 -> 1,0-> 2, 1 -> 2, 2 -> 0, 2 -> 3, 3 -> 3 Output: Yes Explanation: Diagram: 1 The diagram clearly shows a cycle 0-> 2 -> 0 Input:n = 4, e = 4 0 -> 1, 0 -> 2, 1 -> 2, 2 -> 3 Output:No Explanation: Diagram: 3 The diagram clearly shows no cycle
