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. Input:the first line contains a number nn...

The selection sort algorithm sorts an array by repeatedly finding the minimum element (considering ascending order) from the unsorted part and putting it at the beginning. The array will have two parts in this process. A subarray which is sorted and other subarrays which is yet to be sorted....
、、、 我试图在python中实现一个SelectionSort算法,因此我创建了一个numpy数组,并希望将它作为参数传递到算法中。def SelectionSort(array=None): for j in range(i+1,len(array)(np.array([2,5,6,3,7,2,4])) <ipython-input-11-a238fe8a1004> in SelectionSort(array, 浏览4提问于2020-12-25得...

If a key function is specified, the order of elements in the selection may not match their order in the document; use selection.order or selection.sort as needed. For more on how the key function affects the join, see A Bar Chart, Part 2 and Object Constancy....
To see how the selection sort looks in action, try out the SelectSort Workshop applet. The buttons operate the same way as those in the BubbleSort applet. Use New to create a new array of 10 randomly arranged bars. The red arrow called outer starts on the left; it points to the left...

Comparing with the Insertion Sort implementation, the Selection Sort implementation is much slower. As a reference, results from an older computer are listed below: Array size: 1000 Average sorting time: 38 milliseconds Number of tests: 1000 Performance: 38.0 O(N) microseconds Performance: ...
