题目描述

Recently Maxim has found an array of nn integers, needed by no one. He immediately come up with idea of changing it: he invented positive integer xx and decided to add or subtract it from arbitrary array elements. Formally, by applying single operation Maxim chooses integer ii ( 1<=i<=n1<=i<=n ) and replaces the ii -th element of array aia_{i} either with ai+xa_{i}+x or with aixa_{i}-x . Please note that the operation may be applied more than once to the same position.

Maxim is a curious minimalis, thus he wants to know what is the minimum value that the product of all array elements (i.e. ) can reach, if Maxim would apply no more than kk operations to it. Please help him in that.

输入格式

The first line of the input contains three integers n,kn,k and xx ( 1<=n,k<=200000,1<=x<=1091<=n,k<=200000,1<=x<=10^{9} ) — the number of elements in the array, the maximum number of operations and the number invented by Maxim, respectively.

The second line contains nn integers a1,a2,...,ana_{1},a_{2},...,a_{n} () — the elements of the array found by Maxim.

输出格式

Print nn integers b1,b2,...,bnb_{1},b_{2},...,b_{n} in the only line — the array elements after applying no more than kk operations to the array. In particular, should stay true for every 1<=i<=n1<=i<=n , but the product of all array elements should be minimum possible.

If there are multiple answers, print any of them.
