题目描述

Iahub isn't well prepared on geometry problems, but he heard that this year there will be a lot of geometry problems on the IOI selection camp. Scared, Iahub locked himself in the basement and started thinking of new problems of this kind. One of them is the following.

Iahub wants to draw nn distinct points and mm segments on the OXOX axis. He can draw each point with either red or blue. The drawing is good if and only if the following requirement is met: for each segment [li,ri][l_{i},r_{i}] consider all the red points belong to it ( rir_{i} points), and all the blue points belong to it ( bib_{i} points); each segment ii should satisfy the inequality ribi<=1|r_{i}-b_{i}|<=1 .

Iahub thinks that point xx belongs to segment [l,r][l,r] , if inequality l<=x<=rl<=x<=r holds.

Iahub gives to you all coordinates of points and segments. Please, help him to find any good drawing.

输入格式

The first line of input contains two integers: nn ( 1<=n<=1001<=n<=100 ) and mm ( 1<=m<=1001<=m<=100 ). The next line contains nn space-separated integers x1,x2,...,xnx_{1},x_{2},...,x_{n} ( 0<=xi<=1000<=x_{i}<=100 ) — the coordinates of the points. The following mm lines contain the descriptions of the mm segments. Each line contains two integers lil_{i} and rir_{i} ( 0<=li<=ri<=1000<=l_{i}<=r_{i}<=100 ) — the borders of the ii -th segment.

It's guaranteed that all the points are distinct.

输出格式

If there is no good drawing for a given test, output a single integer -1. Otherwise output nn integers, each integer must be 0 or 1. The ii -th number denotes the color of the ii -th point (0 is red, and 1 is blue).

If there are multiple good drawings you can output any of them.
