Algorithms & Programming Fundamentals
What is the result of concatenating the string "Code" with the integer 2021 in most programming languages that support automatic type conversion?
If you concatenate strings using the + operator in a loop that runs n times, how does time complexity generally scale with n?
What could cause unexpected behavior when accessing individual characters in a string based on indexing?
What is returned by calling "environment".substring(10)?
If a programmer needs to encode a character sequence into Unicode values, which step is unnecessary in this process?
Given a list of strings, which algorithm would generally require more comparisons to determine if a particular string is present when the list size increases?
How does String comparison using equals() differ from using == in Java-based languages?
How are we doing?

Suppose String fruit = "banana"; What is the result of fruit.substring(2, 5)?
When implementing unit tests for a function designed to reverse strings, what edge case should be included to ensure it can handle extreme conditions?
Which operation would you use to determine how many characters are in the string "Hello"?
