Implementing a Stack in python

Iterating over a custom ‘Jagged Array’ in Python
A jagged array is an array whose elements are arrays. The elements of a jagged array can be of different dimensions and sizes. A jagged array is sometimes called an "array of arrays." C# natively differentiates between a jagged and a multidimensional array. To iterate over a every single element of a Jagged Array in […]
