Welcome to today's session on "Mastering Array Traversal and Manipulation in Go". Multidimensional arrays in Go are like an 'apartment building' with floors (the outer array) and apartments on each floor (the inner array). Today, our goal is to enhance your understanding of these 'apartment buildings' and how to effectively manage them using Go's syntax and data structures.

In Go, we create a multidimensional array by defining arrays containing arrays. Let's see how to create and work with 2D arrays.

Indices in Go arrays, like in many programming languages, are 0-based. To access a specific element, we specify the indices. For example, visiting the apartment on the second floor (index 1) and delivering a package to the first unit (index 0):

We've accessed the element 4 in the array by its row and column indices.

In Go, to determine the number of rows (floors) and columns (apartments per floor), we use the len function, which returns the length of an array dimension.

To visit each floor (outer array) and each apartment on each floor (inner array), we use nested loops.

Continuing with the apartment building analogy, to replace an element (such as a locker code), modify it directly using its indices.

In Go, to add a new row or column to an array, we often use slices since arrays are of fixed size. Here's how you can simulate adding a row:

To remove a row or column in Go, you can manipulate slices by re-slicing or appending slices that exclude the unwanted element.

Today, we covered various operations on multidimensional arrays in Go, starting from their creation to methods of updating them using Go's syntax. We also learned how to visit each floor and apartment using loops. Enrich your learning experience by experimenting with these concepts in practical exercises focusing on multidimensional arrays in Go. Enjoy your coding journey!
