Study Guide Overview
This study guide covers core string algorithms in Java. It reviews using for loops, indices, and the substring() method for string manipulation. Key algorithms covered include reversing a string, getting all substrings of length N using a sliding window approach, and checking for a substring using equals(). Important string methods like length(), substring(), and equals() are also explained.

Welcome! This guide is designed to be your ultimate resource for string algorithms right before the exam. Let's get you feeling confident and ready to ace those questions!
# String Algorithms Overview
The core of string manipulation often involves using for loops to iterate through characters and substrings. Understanding how to use indices and the substring() method is crucial.
When tackling string algorithm problems, always start by tracing the algorithm with a short example string (like "cat" or "dog"). This helps you visualize the process and catch errors early.
#Key String Methods
length(): Returns the length of the string.substring(int beginIndex, int endIndex): Returns a substring starting atbeginIndex(inclusive) and ending atendIndex(exclusive).equals(String other): Checks if two strings have the same sequ...
