Mahya loves
to know more about the history of her country. She is in particular terested in the history of the ancient kings of Persia.
Recently, Mahya got curious
to know how long each of her favorite
kings had lived. So, she started searching the web, and collecting
information about the kings lives.

Unfortunately, in most cases, the exact dates on which the kings were born or died are not available in resources. So, Mahya could only find some ranges for possible
dates of birth and death for each of the kings. For example, for Cyrus the Great, she could only find that the
date of birth was between
600 BC and 575 BC, and the date of death was 530 BC. So,
she concluded that Cyrus the Great had lived at least 45 years and at most 70 years.

Mahya has created a long list of her favorite kings,
and for each king, has written down two ranges showing the birth range and the death range of that king. Since the list is a bit lengthy, she needs your help to process the list, and produce for each
king the minimum and the maximum age. Note
that if a king was born in year
*x *and died in year *y*, then he lived *y **– **x *years.

## Input

There are multiple test cases in the input. Each test case consists of a line containing four integers *a, b, c, d*, where *−*5000 ⩽ *a** *⩽ *b < c *⩽ *d *⩽ 2000. The range [*a, b*] shows the birth range, and [*c, d*] shows the death range. The input terminates
with 0 0 0 0 which should
not be processed.

## Output

For
each test case, output a line containing the minimum and the maximum
age as two integers separated
by a space.
