Consider a permutation$$$^{\text{∗}}$$$ $$$p_1, p_2, \ldots, p_n$$$ of integers from $$$1$$$ to $$$n$$$. We can introduce the following sum for it$$$^{\text{†}}$$$:

$$$$$$S(p) = \sum_{1 \le l \le r \le n} \min(p_l, p_{l + 1}, \ldots, p_r)$$$$$$

Let us consider all permutations of length $$$n$$$ with the maximum possible value of $$$S(p)$$$. Output the $$$k$$$-th of them in lexicographical$$$^{\text{‡}}$$$order, or report that there are less than $$$k$$$ of them.

Input format:
Each test contains multiple test cases. The first line contains the number of test cases $$$t$$$ ($$$1 \le t \le 10^4$$$). The description of the test cases follows.

The only line of each test case contains two integers $$$n$$$ and $$$k$$$ ($$$1 \le n \le 2 \cdot 10^5$$$; $$$1 \le k \le 10^{12}$$$) — the length of the permutation and the index number of the desired permutation.

It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10 ^ 5$$$.
Output format:
For each test case, if there are less than $$$k$$$ suitable permutations, print $$$-1$$$.

Otherwise, print the $$$k$$$-th suitable permutation.
Example Input 0:
6
3 2
3 3
4 11
4 6
6 39
7 34

Example Output 0:
1 3 2 
2 3 1 
-1
2 4 3 1 
-1
2 3 4 5 7 6 1

Notes:
Let us calculate the required sum for all permutations of length $$$3$$$ (ordered lexicographically):

PermutationValue of $$$S(p)$$$$$$[1, 2, 3]$$$$$$10$$$$$$[1, 3, 2]$$$$$$10$$$$$$[2, 1, 3]$$$$$$9$$$$$$[2, 3, 1]$$$$$$10$$$$$$[3, 1, 2]$$$$$$9$$$$$$[3, 2, 1]$$$$$$10$$$

In the first test case, you have to print the second suitable permutation of length $$$3$$$. Looking at the table, we see that it is the permutation $$$[1, 3, 2]$$$.

In the second test case, you have to print the third suitable permutation of length $$$3$$$. Looking at the table, we see that it is the permutation $$$[2, 3, 1]$$$.
