向集合中添加新元素
Adding new elements to a Set
如何在 Julia 中将新元素附加到 Set？对于数组，这可以通过 append
完成
A = [1, 2, 3] # Array
S = Set(A) # Set
append!(A, 4) # Works
append!(S, 4) # Does not work
对未排序的集合使用push!
julia> S = Set([1, 2, 3])
Set{Int64} with 3 elements:
2
3
1
julia> push!(S, 4)
Set{Int64} with 4 elements:
4
2
3
1
