Commercial Real Estate Co Interview Questions and Answers

The question is about finding the minimum steps to reach from a source string to a destination string using three operations.

• BFS and DFS are graph traversal techniques that can be used to solve this problem.

• BFS is typically used when finding the shortest path or exploring all possible paths in a graph.

• DFS is useful when searching for a specific path or exploring deeply into a graph.

• In this case, BFS can be used to find the minimum steps to reach the destination string.

To print a tree in anticlockwise direction, start from the bottom left and traverse each level from right to left.

• Start from the bottom left of the tree

• Traverse each level from right to left

• Print the nodes as you traverse

Floor value of square root of a number is the largest integer less than or equal to the square root.

• The floor value of square root of a number can be found using mathematical functions like floor() or integer division.

• For example, the floor value of square root of 16 is 4, as sqrt(16) = 4.

• For non-perfect square numbers, the floor value of square root can be calculated using approximation methods.

Find the highest floor from where an egg won't break, given k floors and n eggs.

• Use binary search to minimize the number of drops.

• Start from the middle floor and drop the egg.

• If it breaks, search in the lower half, else search in the upper half.

• Repeat until the highest floor is found.

Object-oriented concepts involve creating classes and objects to organize and structure code.

• Classes define the properties and behaviors of objects

• Objects are instances of classes that can interact with each other

• Inheritance allows for the creation of subclasses that inherit properties and behaviors from a parent class

• Polymorphism allows for objects to take on multiple forms and behave differently depending on the context

• Encapsulation involves hiding the implementation detail...read more
