We can convert it to the list of characters using list() built-in function. When converting a string to list of characters, whitespaces are also treated as characters. Also, if there are leading and trailing whitespaces, they are part of the list elements too. s = 'abc$ # 321 ' ...
Now we will show how to reference items of a two-dimensional array. This is an array that contains rows and columns. We will create a two-dimensional array and then show how to reference each individual item in the array. Next, we create an array, called originalarray, that goes from 0...
In Scala, lists are immutable data structures in which adding new elements is not allowed. So, here we will solve this problem that is generally done in functional programming paradigms. To add elements to a listthere are two methods,
