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。
这样,我们需要得到某个数的位置的时候,直接通过map得到。 1. 2. 3. 1publicclassSolution {2publicintminSwaps(int[] elems) {3intcounter =0;4Map<Integer, Integer> map =buildMap(elems);5int[] copy =newint[elems.length];6System.arraycopy(elems,0, copy,0, elems.length);7Arrays.sort(elems)...
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, ...

对一个数组进行排序是在业务开发中使用非常频繁的功能,Go语言提供了sort.Sort函数,提供高效的排序功能支持,但它要求目标数组必须要实现 sort.Interface接口。 // An implementation of Interface can be sorted by the routines in this package.// The methods refer to elements of the underlying collection by in...
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
