Description

Given n ranges, your task is to determine for each range if it contains some other range and if some other range contains it.

Range [a,b] contains range [c,d] if a≤c and d≤b.

Input Format

The first input line has an integer n: the number of ranges.

After this, there are n lines that describe the ranges. Each line has two integers x and y: the range is [x,y].

You may assume that no range appears more than once in the input.

Output Format

First print a line that describes for each range (in the input order) if it contains some other range (1) or not (0).

Then print a line that describes for each range (in the input order) if some other range contains it (1) or not (0).
