Getting symmetric difference of elements of sets in Julia – symdiff() and symdiff!() Methods

The symdiff() is an inbuilt function in julia which is used to construct the symmetric difference of elements in the passed in sets. 

Syntax: symdiff(s, itrs…)
Parameters:

• s: Specified first set.
• itrs: Specified second set.

Returns: It returns the symmetric difference of elements in the passed in sets. 

Example:

Python

# Julia program to illustrate
# the use of symdiff() method

# Getting the symmetric difference of
# elements in the passed in sets.
println(symdiff([1, 4, 6], [1, 3, 5]))
println(symdiff([1, 2, 3, 4], [0, 1, 2, 3]))
println(symdiff(unique([1, 2, 1]), unique([2, 1, 2])))

Output:

[4, 6, 3, 5]
[4, 0]
Int64[]

symdiff!():

The symdiff!() is an inbuilt function in julia which is used to construct the symmetric difference of the passed in sets, and overwrite the specified set s with the result. 

Syntax:
symdiff!(s::Union{AbstractSet, AbstractVector}, itrs…)
Parameters:

• s: Specified set.
• itrs: Specified iterable.

Returns: It returns the symmetric difference of the passed in sets. 

Example:

Python

# Julia program to illustrate
# the use of symdiff !() method

# Getting the symmetric difference of
# elements in the passed in sets and
# overwrite s with the result
println(symdiff !([1, 4, 6], 1:2))
println(symdiff !([1, 2, 3, 4], [0, 1, 2, 3]))
println(symdiff !(unique([1, 2, 1]), unique([2, 1, 2])))

Output:
