Jagged array

[[File:Jagged Array Representation.png|thumb|right|alt=numArr = [[1, 2, 3], [4, 5, 6, 7], [8, 9 |Memory layout of a jagged array In computer science, a jagged array, also known as a ragged array or irregular array is an array of arrays of which the member arrays can be of different lengths, producing rows of jagged edges when visualized as output. In contrast, two-dimensional arrays are always rectangular so jagged arrays should not be confused with multidimensional arrays, but the former is often used to emulate the latter. Jagged array can be implemented with Iliffe vector data structure in languages such as Java, PHP, Python (multidimensional lists), Ruby, C#.NET, Visual Basic.NET, Perl, JavaScript, Objective-C, Swift, and Atlas Autocode.
