Input

Enter a total of two lines, the first behavior of an integer n,n indicates the number of items, 1<=n<=100000. The second behavior n a positive integer separated by a space, representing the number of the first rank of n items.

Output

Output a total line, n spaces separated by a positive integer p1,p2,p3 ... The PN,PI represents the position of the article I small before the first I operation. Note: If a small item of I has been placed in the correct position Pi before the first operation, we will reverse the interval [PI,PI] (single item).

Solution

Splay Basic Operation ...

We first order the given sequence, the first keyword is the number, the second keyword is a timestamp, and then use the splay to maintain the sequential sequence can be

Or you can consider maintaining min and Pos

Splay to write often! It's as slow as * *
