You are given an integer sequence of length n, a_1, ..., a_n. Let us consider performing the following n operations on an empty sequence b.
The i-th operation is as follows:
Find the sequence b obtained after these n operations.
Input is given from Standard Input in the following format:
n a_1 a_2 ... a_n
Print n integers in a line with spaces in between. The i-th integer should be b_i.
4 1 2 3 4
4 2 1 3
Thus, the answer is 4 2 1 3
.
3 1 2 3
3 1 2
As shown above in Sample Output 1, b becomes 3, 1, 2 after step 2 of the third operation. Thus, the answer is 3 1 2
