cnt后然后cnt多的给大的权重这样
比昨天简单
昨天好难

def maximumImportance(self, n: int, roads: List[List[int]]) -> int:
    cnt = [0 for _ in range(n)]
    for road in roads:
        node1, node2 = road
        cnt[node1] += 1
        cnt[node2] += 1
    cnt.sort()
    ans = 0
    for i in range(n):
        ans += (i+1)*cnt[i]
    return ans
