This study guide covers 2D array traversal using nested for loops. It explains row-major and column-major traversals, including forward and reverse directions. It also covers standard algorithms applied to 2D arrays like searching, modifying values, putting values into other data structures (ArrayLists and Arrays), finding minimum/maximum, sum, mean, mode, checking properties, accessing consecutive sequences, and checking for duplicates.

Question 1 of 16
Why do we use nested loops when traversing a 2D array? 🤔
To access elements randomly
To iterate through rows and columns
To modify array values using enhanced loops
To avoid using enhanced for loops
