Getting intersection of sets in Julia – intersect() and intersect!() Methods

The intersect() is an inbuilt function in julia which is used to construct the intersection of the specified sets.

Syntax:

 intersect(s, itrs...)

Parameters:

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

Returns: It returns the constructed intersection of the specified sets. 

Example:

Python

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

# Getting the intersection of sets.
println(intersect([1, 4, 6], [1, 3, 5]))
println(intersect([1, 2, 3, 4], [0, 1, 2, 3]))
println(intersect(Set([2, 3]), BitSet([3, 4])))

Output:

intersect!()

The intersect!() is an inbuilt function in julia which is used to intersect all passed in sets and overwrite s with the result.

Syntax:

intersect!(s::Union{AbstractSet, AbstractVector}, itrs...)

Parameters:

• s: Specified set.
• itrs: Specified iterator.

Returns: It returns the elements which intersect all passed in sets. 

Example:

Python

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

# Getting the elements which
# intersect all passed in sets.
println(intersect !([1, 4, 6], [1, 3, 5]))
println(intersect !([1, 2, 3, 4], [0, 1, 2, 3]))
println(intersect !(Set([2, 3]), BitSet([3, 4])))

Output:
