Question
You are given an array segments consisting of N
integers denoting the lengths of several segments. Your
task is to find among them four segments from which a
rectangle can be constructed. What is the minimum.
absolute difference between the side lengths of the
constructed rectangle?
Write a function:
int solution (intl segments); that, given an array
segments, returns the minimum absolute difference
between the side lengths of the constructed rectangle
or -1 if no rectangle can be constructed.
Examples:
1. For segments = [2, 2, 2, 2, 21, we can construct only a
2 x2 rectangle out of the given segments. The function
should return O.
2. For segments = [911, 1, 3, 1000, 1000, 2, 2, 999,
1000, 911, we can construct three rectangles: 2 x 911, 2
x 1000, and 911 x 1000. Out of those three possibilities,
the best one is 911 x 1000. The function should return
89.
3. For segments = [4, 1, 1, 1, 3], we cannot construct any
rectangle out of the given segments. The function
should return -1.
