Get the symmetric difference of the given lists
ResourceFunction["MultisetSymmetricDifference"][L1,L2,…] gives the list of elements that occur an odd number of times in the lists L1,L2,…. |
Here is the symmetric difference of two sets:
In[1]:= | ![]() |
Out[1]= | ![]() |
Another example:
In[2]:= | ![]() |
Out[2]= | ![]() |
Like Union, Intersection, and Complement, a single list is pruned of duplicates and sorted:
In[3]:= | ![]() |
Out[3]= | ![]() |
Define two lists, one with a duplicated element:
In[4]:= | ![]() |
The lists are equal up to duplicates, so the set symmetric difference is empty:
In[5]:= | ![]() |
Out[5]= | ![]() |
The element 1 occurs an odd number of times in the multiset sum of the lists:
In[6]:= | ![]() |
Out[6]= | ![]() |
Therefore, 1 is in the multiset difference:
In[7]:= | ![]() |
Out[7]= | ![]() |
