陣列到處都是。索引是陣列的基礎。 但是索引通常只是用來選取一個元素。 我們將進一步探索索引，並從計算多個索引來了解如何旋轉和反轉陣列。 之後我們討論陣列思考的廣義概念。 我們將從1開始，從基礎往上蓋。 我們將使用互動式的陣列語言/符號（APL），並一路學習它的原理。
Arrays are all around us and indexing is fundamental to arrays. However indexing is often only used to select a single element. We'll explore indexing further and see how to rotate and reverse arrays by computing over multiple indices. Then we'll discuss the general idea of array thinking. We'll start from 1 and build from basics. We'll use an interactive language/notation for arrays (APL) and learn how it works along the way.
