Editing the Linux command line is not always a matter of serious formality. You can totally entertain yourself with it. Let's discuss the characteristics of the Linux command line with you.Assume: All examples in this article use Ubuntu Linux. The command line feature described in this article may be the default in your Linux system.Int

Zoj 3813 Alternating Sum (line segment tree), zoj3813
Link: zoj 3813 Alternating Sum
Given a P, S is an infinite string that uses P as a loop and defines G (I, j). Now there are two operations:
1 x d; change the position of x in P to d
2 l r: query the sum of all G (I, j) values between l-r in S.
Solution: Modify the interval query points of the Line Segment tree.According to the G (I, j) formula, you can export: each query l ~ The answer to the r interval is:
Odd Number:
Sortedlist class: a set of key/value pairs. Similar to a hash table, the difference is that the key array in sortedlist is sorted.
