Brian is a great mathematician. He recently managed to enter in world’s top 10 mathematician. His parents wanted to appreciate him and present him a Directed Acyclic Graph. He'd like to customize his graph. He wanted to add as many edges as possible in order to still have a DAG. Please, help Brian to write a python code, to find the maximum number of edges he can add to his graph without obtaining any cycle. Test your code on the following test case: 3 010 000 100 Output: 4 0 4 2 4
