Getting union of sets in Julia - union() and union!() Methods Last Updated : 26 Mar, 2020 Comments Improve Suggest changes Like Article Like Report The union() is an inbuilt function in julia which is used to construct the union of the specified sets. Syntax: union(s, itrs...) Parameters: s: Specified first set. itrs: Specified second set. Returns: It returns the constructed union of the specified sets. Example: Python # Julia program to illustrate # the use of union() method # Getting the constructed union of the specified sets. println(union([5, 10], [15, 20])) println(union([2, 4], [2, 4, 6])) println(union([1, 3], 5:7)) println(union(Set([2, 4, 6]), 1:5)) Output: [5, 10, 15, 20] [2, 4, 6] [1, 3, 5, 6, 7] [4, 2, 6, 1, 3, 5] union!() The union!() is an inbuilt function in julia which is used to construct the union of passed in sets and overwrite s with the result. Syntax: union!(s::Union{AbstractSet, AbstractVector}, itrs...) Parameters: s: Specified set. itrs: Specified iterator. Returns: It returns the constructed union of passed in sets and overwrite s with the result. Example: Python # Julia program to illustrate # the use of union !() method # Getting constructed union of passed # in sets and overwrite s with the result. s1 = Set([1, 2, 3, 4]); union !(s1, 5:7:9); println(s1) s2 = Set([1, 2, 3, 4]); union !(s2, 1:2:3); println(s2) Output: Set([4, 2, 3, 5, 1]) Set([4, 2, 3, 1]) Comment More infoAdvertise with us Next Article Getting union of sets in Julia - union() and union!() Methods K Kanchan_Ray Follow Improve Article Tags : Julia Similar Reads Learn Free Programming Languages In this rapidly growing world, programming languages are also rapidly expanding, and it is very hard to determine the exact number of programming languages.
