In python

You are given a maze with N cells. Each cell may have multiple entry points but not more than one exit (ie. entry/exit points are unidirectional doors like valves). The cells are named with an integer value from 0 to N1. You have to find: Find the node number of maximum weight node (Weight of a node is the sum of node numbers of all nodes pointing to that node) INPUT FORMAT 1. An integer T, denoting the Aumber of testcases, followed by 2T lines, as each testcase will contain 2 lines. 2. The first line of each testcase has the number of cells N. 3. The second line of each testcase has a list of N values of the edge[] array. edge[i] contains the cell number that can be reached from of cell 'i' in one step. edge[i] is 1 if the 'i'th cell doesn't have an exit. OUTPUT FORMAT 1. First line denotes the node number with maximum wight node.
