Before implementing Java program for selection sort let's first see how selection sort functions to sort array elements in either ascending or descending order.Selection sortimproves a little on the bubble sort by reducing the number of swaps necessary fromO(N2)toO(N). However, the number of ...
选择排序(Selection-sort)是一种简单直观的排序算法。它的工作原理:首先在未排序序列中找到最小(大)元素,存放到排序序列的起始位置,然后,再从剩余未排序元素中继续寻找最小(大)元素,然后放到已排序序列的末尾。以此类推,直到所有元素均排序完毕。 算法描述 n个记录的直接选择排序可经过n-1趟直接选择排序得到有序结...

Selection sort in Java Max-min sorting Let's say that an array is max-min sorted if the first element of the array is the maximum element, the second is the minimum, the third is the second maximum and so on. Modify Selection sort such that it can be used for max-min sorting....

In the selectSort.java program, the data items with indices less than or equal to out are always sorted. Efficiency of the Selection Sort The selection sort performs the same number of comparisons as the bubble sort: N*(N-1)/2. For 10 data items, this is 45 comparisons. However, 10...
