COCI '07 Contest 2 #4 Turbo
View as PDFFrane has been given the task of sorting an array of numbers. The array consists of  integers, each
between 
 and 
 (inclusive), with each of those appearing exactly once in the array. Frane has come up
with the following sorting algorithm which operates in 
 phases, and named it turbosort:
- In the first phase, the number 
is moved to position
by repeatedly swapping consecutive elements.
 - In the second phase, the number 
is moved to position
in the same manner.
 - In the third phase, the number 
is moved to position
.
 - In the fourth phase, the number 
is moved to position
.
 - And so on.
 
In other words, when the number of the phase is odd, Frane will choose the smallest number not yet chosen, and move it to its final position. In even phases he chooses the largest number not yet chosen.
Write a program which, given the initial array, output the number of swaps in each phase of the algorithm.
Input Specification
The first line contains an integer  
, the number of elements in the array.
Each of the following 
 lines contains an integer between 
 and 
 (inclusive), the array to be sorted.
The array contains no duplicates.
Output Specification
For each of the  phases, output the number of swaps on a single line.
Scoring
In test cases worth  of points, 
 will be less than 
.
