Challenge 3: Find Symmetric Pairs in an Array
Explore how to find symmetric pairs in a 2D array by implementing a function in C#. Understand the concept of symmetric pairs and practice applying hashing strategies to solve the problem efficiently. This lesson helps you develop a step-by-step approach to algorithm design and coding for a common interview challenge.

Problem statement
By definition, (a, b) and (c, d) are symmetric pairs if a = d and b = c. In this problem, you have to implement the string findSymmetric(int [,]arr, ...
