题目描述

This problem is the most boring one you've ever seen.

Given a sequence of integers a1,a2,...,ana_{1},a_{2},...,a_{n} and a non-negative integer hh , our goal is to partition the sequence into two subsequences (not necessarily consist of continuous elements). Each element of the original sequence should be contained in exactly one of the result subsequences. Note, that one of the result subsequences can be empty.

Let's define function f(ai,aj)f(a_{i},a_{j}) on pairs of distinct elements (that is iji≠j ) in the original sequence. If aia_{i} and aja_{j} are in the same subsequence in the current partition then f(ai,aj)=ai+ajf(a_{i},a_{j})=a_{i}+a_{j} otherwise f(ai,aj)=ai+aj+hf(a_{i},a_{j})=a_{i}+a_{j}+h .

Consider all possible values of the function ff for some partition. We'll call the goodness of this partiotion the difference between the maximum value of function ff and the minimum value of function ff .

Your task is to find a partition of the given sequence aa that have the minimal possible goodness among all possible partitions.

输入格式

The first line of input contains integers nn and hh (2<=n<=105,0<=h<=108)(2<=n<=10^{5},0<=h<=10^{8}) . In the second line there is a list of nn space-separated integers representing a1,a2,...,ana_{1},a_{2},...,a_{n} (0<=ai<=108)(0<=a_{i}<=10^{8}) .

输出格式

The first line of output should contain the required minimum goodness.

The second line describes the optimal partition. You should print nn whitespace-separated integers in the second line. The ii -th integer is 11 if aia_{i} is in the first subsequence otherwise it should be 22 .

If there are several possible correct answers you are allowed to print any of them.

说明/提示

In the first sample the values of ff are as follows: f(1,2)=1+2+2=5f(1,2)=1+2+2=5 , f(1,3)=1+3+2=6f(1,3)=1+3+2=6 and f(2,3)=2+3=5f(2,3)=2+3=5 . So the difference between maximum and minimum values of ff is 11 .

In the second sample the value of hh is large, so it's better for one of the sub-sequences to be empty.
