Why is 20 expected in this test case, when 61 gives the minimal number of nodes that are infected?
I do not have any clue why the judge system exptects 20 but not 61, the test data is below the code. I generated the answer for every i from initial and printed
I do not have any clue why the judge system exptects 20 but not 61, the test data is below the code. I generated the answer for every `i` from `initial` and printed how many nodes had been covered in each case with the following code:\n\n```\n    // First, convert the graph list into a more convenient\n    // representation. For each gr[i], remove all the zeros and leave\n    // only the i32 values indicating the nodes being connected.\n\n    for val in graph.iter_mut() {\n        val.reserve(val.len());\n        let mut filtered: Vec<i32> = Vec::new();\n        for (j, inner_val) in val.iter_mut().enumerate() {\n            if *inner_val == 1 {\n                filtered.push(j as i32); }\n        }\n        val.drain(0..val.len());\n        val.append(&mut filtered);\n    }\n\t\n    for t in &initial {\n        let mut debug_initial =\n            initial.clone().into_iter().filter(|e| {\n                if *e == *t { false }\n                else { true }\n            }).collect::<std::collections::vec_deque::VecDeque<i32>>();\n        println!("Vec w/o {} {:?}", t, debug_initial);\n        let mut debug_initial_counter: i32 = 0;\n        let mut vis_debug: std::collections::HashSet::<i32>\n            = std::collections::HashSet::new();\n        while debug_initial.len() > 0 {\n            let current_node = debug_initial.pop_front().unwrap();\n            vis_debug.insert(current_node);\n            for next in &graph[current_node as usize] {\n                if vis_debug.contains(&next) { continue; }\n                vis_debug.insert(*next);\n                debug_initial.push_back(*next);\n                debug_initial_counter += 1;\n            }\n        }\n\n        println!("The

is the output of the program:\nVec w/o 20 [38, 60, 40, 61, 50]\nThe infected nodes w/o 20 61\nVec w/o 38 [20, 60, 40, 61, 50]\nThe infected nodes w/o 38 61\nVec w/o 60 [20, 38, 40, 61, 50]\nThe infected nodes w/o 60 61\nVec w/o 40 [20, 38, 60, 61, 50]\nThe infected nodes w/o 40 61\nVec w/o 61 [20, 38, 60, 40, 50]\nThe infected nodes w/o 61 60\nVec w/o 50 [20, 38, 60, 40, 61]\nThe infected nodes w/o 50 61\n\nAs I said, why does the judge system expects 20, when 61 is better?
