WebVamos dar um exemplo: Let the initial directed graph be as below Let's start our path from 0. Thus, curr_path = {0} and circuit = {} Now let's use the edge 0->1 Now, curr_path = {0,1} and circuit = {} similarly we reach up to 2 and then to 0 again as Now, curr_path = {0,1,2} and circuit = {} Then we go to 0, now since 0 haven't got any unused ...
