The attached figure represents the array for 237 x 43
<h3>How to draw the array?</h3>
The array is given as:
237 x 43
An array is represented as:
Row x Column
This means that:
Row = 237
Column = 43
i.e. the array has 237 rows and 43 columns
The numbers are large, so the cells would be small when the arrays are drawn
See attachment for the array
