C++ has support for C-style strings, but it is preferable to use C++ style strings in pure C++ code. This terminating character marks the end of the string within the array, or buffer. A special terminating character is stored directly after the last character of the string.

Using Java's StringBuilder or Python’s `.join` provides a linear time solution for multiple string concatenations.Īnother class of strings are C-style strings, so named as they are used in the C language. In Python, generally the `.join` method on strings should be used, which accepts an iterable of multiple strings. Java provides a mutable StringBuilder class, which should be used for concatenating multiple strings. This has performance implications for string concatenation when joining a number of strings, running in quadratic time. Immutable strings require a new string to be created if any changes are made. Python and Java provide an immutable string type. 4.1.1 Types of strings (Java, Python, C++)Ĭ++ provides a mutable string, meaning the string contents can be changed after creation. Earlier systems used ASCII encoding, with Unicode encoding used in later systems. The bytes are encoded using some character encoding. In most languages, strings are implemented using an array of bytes. It is usually considered a data type and is often included as part of language primitives. 4.1 What is a string?Ī string is an ordered sequence, or string, of characters.

You will likely be given more time if you are expected to create a full solution.ģ.7 Serialize and Deserialize Binary Tree

Similar to the medium section, these more difficult questions may be asked in an onsite or video call interview.

You should be prepared to write code or sketch out the solutions on a whiteboard if asked.Ģ.1 Longest Substring Without Repeating CharactersĢ.4 Letter Combinations of a Phone NumberĢ.15 Longest Substring with At Least K Repeating Characters Here are some moderate-level questions that are often asked in a video call or onsite interview. These questions are often asked during the ‘phone screen’ stage, so you should be comfortable answering them without being able to write code or use a whiteboard.ġ.8 Count Substrings with Only One Distinct Letter Here are some of the easiest questions you might get asked in a coding interview. Don’t get stuck in a loop of reading as many solutions as possible! We’ve analyzed dozens of questions and selected ones that are commonly asked and have clear and high quality answers. If you get stuck, go ahead and look at the solutions, but then try the next one alone again. Begin by writing your own solution without external resources in a fixed amount of time. Instead, you should use these questions to practice the fundamental concepts of strings.Īs you consider each question, try to replicate the conditions you’ll encounter in your interview. Interviewers will always try to find new questions, or ones that are not available online. You might be tempted to try to read all of the possible questions and memorize the solutions, but this is not feasible.
