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

Getting exclusive elements of a set in Julia – setdiff() and setdiff!() Methods

Last Updated : 25 Apr, 2025

The setdiff() is an inbuilt function in julia which is used to returns the elements which are in first set but not in second set.

Syntax:

setdiff(s, itrs...)

Parameters:

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

Returns: It returns the elements which are in first set but not in second set.

Example:

Python

# Julia program to illustrate 
# the use of setdiff() method
  
# Getting the elements which are
# in first set but not in second set.
println(setdiff([1, 4, 6], [1, 3, 5]))
println(setdiff([1, 2, 3, 4], [0, 1, 2, 3]))
println(setdiff(Set([2, 3]), BitSet([3, 4])))

Output:

setdiff!()

The setdiff!() is an inbuilt function in julia which is used to remove each element of set s which are also in the specified iterable.

Syntax:

setdiff !(s, itrs...)

Parameters:

s: Specified first set.
itrs: Specified iterable.

Returns: It returns the remaining elements of the set s after removal.

Example:

Python

# Julia program to illustrate 
# the use of setdiff!() method
  
# Getting the remaining elements of 
# the set s after removal.
A = Set([1, 2, 3, 4]);
setdiff !(A, 1:2:3);
println(A)
 
B = Set([1, 2, 3, 4, 5, 6]);
setdiff !(B, 1:3:5);
println(B)

Output:

Set([4, 2])
Set([2, 3, 5, 6])
