Triangles
Memory limit: 32 MB
In a finite sequence of positive integers not greater than a billion,
representing lengths of line segments, we want to find three numbers such that
one can build a triangle from segments of such lengths.
Task
Write a program which examines whether among the line segments - lengths of
which are written in the standard input - there exist three such that one can
build a triangle from them. If so, the program writes the lengths of those three
segments in the standard output. If there exist no such triple, the program
writes one word NIE ("no") in the file standard output.
If there exist many triples of line segments of lengths written in the standard
input such that one can build a triangle from them, then your program should
find and write only one (arbitrary) of them.
Input
In the standard input there is a finite sequence of at least three positive
integers not greater then
, terminated by the
number
. Each number is written in a separate line. Positive numbers
are lengths of line segments, and the number
denotes the end of the
data.
The data in the standard input are written correctly and your program need not
verify that.
Output
In the standard output there should be either one word NIE, or three
lengths of line segments chosen from the standard input, from which one can
build a triangle. The lengths are separated by single spaces.
Examples
For the input data:
105
325
55
12555
1700
0
the correct result is:
NIE
For the input data:
250
1
105
150
325
99999
73
0
the correct result is:
250 105 150
