This code performs the following steps:

1. a = [1,2,3]: Creates a list named a containing the elements [1, 2, 3].

2. b = [2,3,4]: Creates another list named b containing the elements [2, 3, 4].

3. c = set(a) & set(b):

   • Converts both lists a and b into sets using set(a) and set(b). This removes any duplicates (if they existed) and allows set operations.
   • The & operator computes the intersection of the two sets, meaning it identifies the elements that are present in both sets.

After the code is executed, c will contain the common elements between a and b. Specifically:

• set(a) will be {1, 2, 3}
• set(b) will be {2, 3, 4}
• The intersection of these sets is {2, 3}.

Thus, c will be {2, 3}.
