+// 1. Problem Statement -------------------------------------------------
+/*
+There are n people standing in a circle, where n is even.
+Each person looks at the person standing exactly opposite to them.
+
+You are given three distinct integers a, b, and c.
+It is known that person a is looking at person b.
+
+Determine the person that person c is looking at.
+If such a person cannot exist, print -1.
+*/
+
+// 2. Approach -----------------------------------------------------------
+/*
+The pair (a, b) fixes the entire circle.
+Once the circle is fixed, every person has exactly one opposite person.
+
+If person c does not fit into this fixed circle, the answer is -1.
+Otherwise, move half the circle from c to find the person they are looking at.

+Space Complexity: O(1)
