June 2, 2024 - 5. What is the difference between str() and repr()? str() is used for creating output for end-users, while repr() is mainly used for development and debugging, providing a more unambiguous representation. 6. How do you find the length of a string? The len() function can be used to find the length of a string: ... 7. Explain the concept of string indexing in Python.

The questions cover topics like reversing strings, reversing order of words, reversing internal contents of words, merging characters of strings, removing duplicate characters, counting character occurrences, and more.

April 15, 2025 - We’re asked to reverse the characters of a given string. For example, reversing "hello" should return "olleh". Now, here’s a question for you: If I gave you a word and asked you to spell it backward, how would you do it? You’d likely go letter by letter, right? That’s essentially what we’ll do here — just in code. ... In Python, slicing is like magic.

April 16, 2025 - def remove_character(s, char_to_remove): return ''.join([char for char in s if char != char_to_remove]) # Using replace # def remove_character(s, char_to_remove): # return s.replace(char_to_remove, '') # Example print(remove_character("hello world", "l")) # Output: "heo word"Code language: Python (python) Run · These questions help assess key programming concepts like string manipulation, algorithm design, and efficiency.

Don't make assumptions about what is in the string, asking these types of questions helps demonstrate your seniority and familiarity with common gotchas. One danger you should be aware of is how languages will abstract away the heavy lifting when it comes to strings. This can make us wrongly assume that "simple" operations are cheap. For example, we can very easily get a substring of a string in Python using the Python slicing syntax: s[1:5]. Writing it this way we may assume that this is a constant-time operation.

Is Unique: Implement an algorithm to determine if a string has all unique characters.

For example, consider a task to find the longest common prefix amongst an array of strings. Finding the longest common prefix amongst an array of strings involves iterating character by character over the strings, starting from the first character. We compare the characters at the same position across all strings until we find a mismatch or reach the end of one of the strings.
