American Express Data Engineering Manager Interview Questions and Answers

The diameter of a tree is the width of the tree trunk measured at breast height (4.5 feet above the ground).

• Diameter is typically measured in inches or centimeters.

• To measure the diameter of a tree, use a measuring tape or calipers at breast height.

• The formula for calculating diameter is circumference divided by pi (3.14).

Calculate the height of a tree using tree traversal algorithm.

• Use depth-first search (DFS) or breadth-first search (BFS) to traverse the tree and calculate the height.

• For DFS, recursively traverse each subtree and return the maximum height of the left and right subtrees.

• For BFS, use a queue to traverse each level of the tree and increment the height at each level.

• The height of a tree is the number of edges on the longe
