To sort an entire array, we need to callMergeSort(A, 0, length(A)-1). As shown in the image below, the merge sort algorithm recursively divides the array into halves until we reach the base case of array with 1 element. After that, the merge function picks up the sorted sub-arrays...
i tried to merge and sort an array which i had gotten with user input but the sort function is not working, i tried same thing with normal specified array, it worked fin

1.介绍 归并排序(MergeSort)是利用归并的思想实现的排序方法,该算法采用经典的分治策略(分治法将问题分(divide)成一些小的问题然后递归求解, 而治(conquer)的阶段则将分的阶段得到的各答案“修补”在一起,即分而治之) 2.示意图 说明:可以看到这种结构很像一颗完全二叉树

merage sort Divide-and-conquer merge sort的核心理念是Divide-and-conquer,这个范式的核心是把问题分割成跟原问题相似的子问题,然后,递归的解决这些子问题,最后把这些子问题的结论合并得到原始问题的答案。Divide-and-conquer分三步: Divide把问题分割成跟原来的问题一致但是规模变小了的子问题。
