How to determine what is a overlap data of data set 1 and data set 2? Simple way.

One simple way to determine the overlap data of data set 1 and data set 2 is to compare the two data sets and identify the values that are present in both sets. Here are the steps to do this:

1. Sort both data sets in ascending order to make it easier to compare them.
2. For each value in data set 1, check if it also exists in data set 2.
3. Keep track of the values that are present in both data sets.
4. Once you have checked all values in data set 1, you will have identified the overlap data.

Alternatively, you can use software tools such as Excel or programming languages like Python to compare and identify the overlap data between the two data sets.
