How do you define a set in Julia?
A set in Julia can be created with a pre-defined keyword Set(). This keyword accepts elements placed within square brackets([]) and creates a set by defining its data type based on the data type of the elements.
What is push in Julia?
When you push!(m,y) you are actually storing into m a reference to the array y , instead of copying the contents. That’s why if you modify an element in y , you will see the change in all of the elements of m : because you are actually looking inside the same y .
What is Julia collect?

What is a dictionary in Julia?
Dictionary in Julia is a collection of key-value pairs, where each value in the dictionary can be accessed with its key.

How do you use a loop in Julia?
For loops are used to iterate over a set of values and perform a set of operations that are given in the body of the loop. For loops are used for sequential traversal. In Julia, there is no C style for loop, i.e., for (i = 0; i < n; i++). There is a “for in” loop which is similar to for each loop in other languages.
What is Union in Julia?
UnionAll types Julia’s type system can also express an iterated union of types: a union of types over all values of some variable. The syntax Array{Int,2} is equivalent to Array{Int}{2} ; internally each UnionAll is instantiated with a particular variable value, one at a time, outermost-first.
How do you create a matrix in Julia?
Julia provides a very simple notation to create matrices. A matrix can be created using the following notation: A = [1 2 3; 4 5 6]. Spaces separate entries in a row and semicolons separate rows. We can also get the size of a matrix using size(A).
How do I use Unicode in Julia?
