Min swaps to sort array Given an array with distinct numbers, return an integer indicating the minimum number of swap operations required to sort the array into ascending order. Example 1: Input: [5, 1, 3, 2]Output: 2Explanation: [5, 1, 3, 2] -> [2, 1, 3, 5] -> [1, 2, ...
每遍历新的一个 vertex 就记录一次 swaps。总的 swaps 应该是遍历的 edge,所以应该是 vertex 的遍历数 - 1。这个环节的技巧是利用graph 反向推导。即从 sorted input 还原到最开始 original position 需要多少 swaps。因为 original order 是已知条件。

Output If it is possible to sort the array in ascending order using any sequence of swaps you are allowed to make, print YES. Otherwise, print NO. Examples input Copy 612534601110 output Copy YES input Copy 612534601010 output Copy NO Note In the first example you may swapa3 anda4, and t...
This bottom-up variation allows for approximately 50% reduction in the number of comparison operations during heap siftdown, without changing the number of swaps, thus making it more efficient. Link: https://lkml.kernel.org/ioyfizrzq7w7mjrqcadtzsfgpuntowtjdw5pgn4qhvsdp4mqqg@nrlek5vmisbu ...

// Swap swaps the elements with indexes i and j.Swap(i, jint)} 这样导致我们对不同元素类型的数组,都需要重复实现这个接口,编写了很多类似的代码。下面是官方给的一个排序的示例,可以看到实现这样的排序功能,要写这么多代码。 typePersonstruct{NamestringAgeint} ...
