Bessie is bored and yet again causing trouble in Farmer John's barn. FJ has $N$ ($1\leq N \leq 10^5$) stacks of haybales. For each $i\in [1,N]$, the $i$th stack has $h_i$ ($1\le h_i\le 10^9$) haybales. Bessie does not want any haybales to fall, so the only operation she can perform is as follows:

• If two adjacent stacks' heights differ by at most $K$ ($1\le K\le 10^9$), she can swap the two stacks.

What is the lexicographically minimum sequence of heights that Bessie can obtain after some sequence of these operations?

Note: the time and memory limits for this problem are 4s and 512MB, twice the defaults.

Input Format

The first line of input contains $N$ and $K$. The $i+1$-st line contains the height of the $i$-th haybale.

Output Format

Please print out $N$ lines, the $i$-th containing the height of the $i$-th haybale in the solution.

Sample Input

5 3
7
7
3
6
2

Sample Output

6
7
7
2
3

One way that Bessie can swap the stacks is as follows:

   7 7 3 6 2
-> 7 7 6 3 2
-> 7 7 6 2 3
-> 7 6 7 2 3
-> 6 7 7 2 3

Scoring

• In 10% of all input cases, $N\le 100$
• In another 20% of all input cases, $N\le 5000$
• In the remaining 70% of input cases, there are no additional constraints
