What is the Big O notation O(1) used to describe?
Answer: An algorithm with constant time complexity regardless of input size
O(1) means the operation takes the same amount of time no matter how large the input is.
What is the purpose of comments in source code?
Answer: To provide human-readable explanations that are ignored by the compiler
Comments are annotations in code intended for human readers; they are skipped by compilers and interpreters.
