在LC上做题的过程中难免要用到排序的函数,常用的排序函数主要有两个:(1)一个是在直接在所需排序的数组arrays上进行升序,即arrays.sort();(2)另一个则是调用sorted()函数对arrays进行升序,不过需要一个变量存放排序后的结果,即arrays_sorted = sorted(arrays). 下面将针对刷题过程中遇到的两三...

merge_sort Method: This is the main function that implements the merge sort algorithm. Base Case: If the array has one or zero elements, it is already sorted, so the function returns the array as is. Divide: The array is divided into two halves using the middle index. Recursion: The me...
