看到这道题,我们会想到使用sort+equal_range函数的配合(n的范围大约在1万---10万左右),不过n<=1000 数据量不大,所以我们可以直接使用count函数,这里我们要注意一点:count函数的复杂度是线性的,最坏情况是O(n)。这题很简单,所以我们很快就可以写出代码: #include<iostream>#include<cstdio>#include<algorithm>#...

2.In the lecture, we count the number of inversions in O(n log n) time, using the Merge-Sort idea. Is it possible to use the Quick-Sort idea instead ? If possible, implement the algorithm in your favourite language, run it over the given file, and compare its running time with the...
