Advanced Programming Interview Questions
- What do you understand by the DRY principle?
- What are constants in programming, and how many types of constants are there?
- What is software testing?
- What is bubble sort, and what is its time complexity?
- List the significant sorting algorithms with their time complexities.
- Write a function that can count the occurrence of a given character in a string.
