qklbishe 小美拿到了一个数组,她每次可以进行如下操作: 选择两个元素,一个加 1,另一个减 1。 小美希望若干次操作后,众数的出现次数尽可能多。你能帮她求出最小的操作次数吗? 众数定义:在一组数据中,出现次数最多的数据,是一组数据中的原数据,而不是相应的次数。 一组数据中的众数不止一个,如数据2、3、-1、2、1、3中,2、3都出现了两次,它们都是这组数据中的众数。 区块链毕设网qklbishe.com为您提供问题的解答 小美拿到了一个数组,她每次可...
qklbishe Сity N. has a huge problem with roads, food and IT-infrastructure. In total the city has n junctions, some pairs of them are connected by bidirectional roads. The road network consists of n - 1 roads, you can get from any junction to any other one by these roads. Yes, you’re right — the road network forms an undirected tree.

The Mayor is going to take a large tax from each restaurant, so he is interested in making the total number of the restaurants as large as possible. Help the Mayor to analyze the situation. Find all such pairs of (a, b) that a restaurants can belong to "iMac D0naldz", b restaurants can belong to "Burger Bing", and the sum of a + b is as large as possible. Recently, the Mayor came up with a way tha...
