In this task, you are given two sets, and you need to count the number of elements at the union of two given sets. A Set is shown by two curly braces and comma-separated numbers inside, like {1, 2, 3}. Union of two given sets is the smallest set which contains all the elements of both the sets. To find the union of two given sets, A and B is a set that consists of all the elements of A and all the elements of B such that no element is repeated.

Set1: '{2, 5, 10, 11, 14, 19}', Set2: '{4, 6, 8, 11, 12, 13, 14, 15}'. How many elements are there in the union of Set1 and Set2 ?
12
Given Set1 as {2, 5, 10, 11, 14, 19} and Set2 as {4, 6, 8, 11, 12 ,13 ,14 ,15}, the union of these two sets is:\n\n{2}\n{5}\n{10}\n{11}\n{12}\n{13}\n{14} \t<- duplicate removed\n{15} \t<- duplicate removed\n{\19}

The elements of the final set should be listed in ascending order. The total number of element is 12..
