How to append a new element to a Set in Julia? For an Array this can be done with append
A = [1, 2, 3] # Array
S = Set(A) # Set
append!(A, 4) # Works
append!(S, 4) # Does not work
Use push!
for an unsorted collection
julia> S = Set([1, 2, 3])
Set{Int64} with 3 elements:
2
3
1
julia> push!(S, 4)
Set{Int64} with 4 elements:
4
