HDFC Bank Interview Questions and Answers

The number of nodes that can be inserted in a tree depends on the type of tree and its implementation.

• The maximum number of nodes in a binary tree is 2^(h+1) - 1, where h is the height of the tree.

• In a balanced binary search tree, the number of nodes can be calculated using the formula 2^(h+1) - 1.

• In a general tree structure, the number of nodes is not limited by a specific formula and can vary based on the implementation and constraints.

Python is a versatile programming language used in web development, data analysis, artificial intelligence, automation, and more.

• Web development (Django, Flask)

• Data analysis (Pandas, NumPy)

Find the largest and smallest strings in an array of strings.

• Iterate through the array and compare each string to find the largest and smallest.

• Use built-in functions like sort() to simplify the process.

• Handle edge cases like empty array or array with only one element.

Arrays are a data structure that stores elements of the same data type in contiguous memory locations, while stacks are a type of data structure that follows the Last In First Out (LIFO) principle.

• Arrays can store elements of different data types, while stacks typically store elements of the same data type.

• Arrays allow random access to elements based on index, while stacks only allow access to the top element.

• Examples: Array - ['apple', 'banana', 'cherry'], Stack - [3, 5, 7]
