There is a disaster in Los Angeles, and all the students at UCLA want to get on a school bus and gather at a shelter outside of Los Angeles. There are several nodes in Daegu, each connected by a road. Each road has a maximum number of buses that it can accommodate, and you need to plan the optimal route to evacuate as many students as possible. Write a program that outputs the maximum number of buses that can reach the shelter given the conditions below. Conditions UCLA has a node number of 0 and the shelter has a node number of n1. The school buses are all traveling on the same road. The direction of the given road is one-way. There are 0 to 2 roads between any two nodes. You believe that there are no roads that lead directly from UCLA to the shelter. There is no way to get to the shelter from UCLA. Input Format On the first line, the number of neighborhoods, n, and the number of roads, m, are given, separated by spaces. (3n250,2m500,n,m are integers) From line 2 to line m+1, the information of each road is given, separated by a space. The road information consists of three integers, which represent the starting zone ai, the ending zone bj, and the vehicle capacity ci of the two zones connected by the road. (1ci1000, where ci is an integer) Output Format Output the maximum number of buses that can reach the shelter on the first line. Write in Python, and use Min-Cut Max-Flow Theorem. Timeout per a testcase 0.36 s. therefore measuring time is necessary. Include it in the code. Important) I would be very grateful if you could attach a screenshot of whether the sample output comes out properly when you put in the sample input
