Consider two arbitrarily chosen horizontal lines. A trapezoid between these lines has two
vertices situated on the upper line and the other two vertices on the lower line (see figure below).
We will denote by
,
,
and
the upper left, upper right, lower left and respectively lower right vertices of the trapezoid
. A subset
of trapezoids is called independent if no two trapezoids from
intersect.
Task
Determine the cardinality of the largest independent set of trapezoids (the largest set means the set
with most elements). Also find the count of different independent sets with maximum cardinality.
Find this count modulo .
Input Specification
The first line of input contains one integer – the number of trapezoids. Each of the next
lines
contains four integers
,
,
and
. No two trapezoids have a common vertex (corner).
Output Specification
The only line of output should contain two numbers separated by space: firstly, the cardinality of
the largest independent set; secondly, the count of different independent sets with maximum
cardinality modulo .
Constraints
- If only the first number in the output is correct you will get
of the test score.
