You just have to complete the function findswaps() , Which takes integer n and an integer array arr of size n and returns the minimum number of swaps required to get maximum number of inversions. 用hashmap去存每个数的索引,然后每次交换即可,是个贪心的题目。 publicstaticintfindswaps(int n,in...

SORT(UNIQUE(array)) For example, to extract unique values in columns A through C and arrange the results from A to Z, use this formula: =SORT(UNIQUE(A2:C10)) Compared to the above example, the output is a lot easier to perceive and work with. For instance, we can clearly see that...
These swaps close one instance of PowerShell and open another so you know you’re in a clean environment (not always true with the ISE); the flip side is you realise it is a clean environment when you want something which was loaded in the shell in the shell I’ve just swapped away ...
