Welcome to today's session on "Multidimensional Arrays and Their Traversal in Kotlin". Multidimensional arrays in Kotlin are arrays that can hold other arrays as their elements. Imagine them as an 'apartment building' with floors (the outer array) and apartments on each floor (the inner array). Our goal today is to strengthen your foundational knowledge of these 'apartment buildings' and how to handle them effectively in Kotlin.

In Kotlin, we use arrays of arrays to construct a multidimensional array. Here are examples demonstrating how to create and work with 2D static arrays.

In Kotlin, all indices in arrays are 0-based. If you want to visit an apartment on the second floor (index 1) and bring a package to the first unit (index 0) in this building, you would do:

We accessed the element 4 in the array using its position. The number [1] refers to the second inner array, and refers to the first element of that array.
