In this course, we'll delve a little deeper into working with data structures such as strings, arrays, and hashes. We'll also learn how to work with blocks, particularly in conjunction with the widely-used iterative methods such as #each, #map, #select, #reduce, and others. Finally, we'll fine-tune our problem-solving process and learn to use it by working on more complex program, and get familiar with using debugging tools.
