Explain linear time complexity.
Time increases linearly with input size, denoted as O(n).
Explain logarithmic time complexity.
Time increases logarithmically with input size, denoted as O(log n).
Explain quadratic time complexity.
Time increases quadratically with input size, denoted as O(n^2).
Describe the concept of modularity in programming.
Breaking down a program into smaller, manageable functions.
What are logic errors in programming?
Mistakes in the program's logic, like incorrect conditions or infinite loops.
What are syntax errors in programming?
Mistakes in the code's grammar, like typos or missing punctuation.
What is the purpose of nested conditionals?
Allows for more complex decision-making based on multiple conditions.
What are some ethical considerations in computing?
