Check if binary tree is balanced or not.
A balanced binary tree has the height of left and right subtrees differ by at most 1.
Recursively check the height of left and right subtrees and compare.
Use a helper function to calculate the height of a subtree.
Time complexity: O(nlogn) for a balanced tree, O(n^2) for a skewed tree.
Detect loops in a linked list.
Use two pointers, one moving at a faster pace than the other.

Use Select() method to select the required columns
Solid design principles are a set of guidelines for writing maintainable and scalable code.
Single Responsibility Principle (SRP) - each class should have only one responsibility
Open/Closed Principle (OCP) - classes should be open for extension but closed for modification
Liskov Substitution Principle (LSP) - subclasses should be able to replace their parent classes without affecting the program's correctness
