The symmetric difference of two sets A and B. denoted by A a B, is the set containing all of the elements of set A and all of the elements of set B that do not belong to both sets. In other words, the symmetric difference of two sets will be the collection of elements which are members of either set, but not both. This is equivalent to taking a union of the sets that excludes their intersection. Therefore, if an element exists in set A, and does not exist in set B, this element should be grouped into the output set representing the symmetric difference. In addition, if an element exists in set B, and does not exist in set A, this element should be grouped into the output set representing the symmetric difference. Any element that exists in both set A and set B should not be grouped into the output set representing the symmetric difference. Task Write out a function, symmetricDifference(arri, arr2), that generates the symmetric difference of two arrays. In adhering to the nature of sets, there will be distinct words within each array. For input, you will be given an array of strings referenced as arri and an array of strings referenced as arr2, representing set A and set B, respectively. Each and every array passed into the function will contain at least one element. For output, you should return an array representing the symmetric difference of arrland arr2
