PureSoftware Software Testing Engineer Interview Questions, Process, and Tips

Time complexity refers to the amount of time taken by an algorithm to run, while space complexity refers to the amount of memory used by an algorithm.

• Time complexity is measured by the number of operations an algorithm performs, while space complexity is measured by the amount of memory an algorithm uses.

• An algorithm with a time complexity of O(n) will take longer to run as the input size increases, while an algorithm ...read more

The 4 pillars of OOP are Abstraction, Encapsulation, Inheritance, and Polymorphism.

• Abstraction: Hiding implementation details and showing only necessary information.

• Encapsulation: Binding data and functions that manipulate it together in a single unit.

• Inheritance: Creating new classes from existing ones, inheriting their properties and methods.

• Polymorphism: Ability of objects to take on multiple forms or behaviors.

A traveling spring structure in a matrix is a pattern where a spring-like structure moves through the matrix.

• The structure moves in a zigzag pattern through the matrix

• The structure can be used to traverse a matrix and visit all its elements

• The structure can be implemented using a combination of loops and conditional statements

• Example: Given a matrix of size n x m, start at the top-left corner and traverse the matrix us...read more
