1,1,1,2,2,2,3,3,3 calculate mode?

Question

DR says
create a sckeleton program to
Find the mode (number that occurs most often), for example,
1, 1, 1, 2, 3, 3, 4, 5
1 is the mode

what if the case was as above

Answer 1

A set of data can have more than one mode. However, at the same time, the mode is the number that appears more frequently than the other.
In 1,1,1,2,2,2,3,3,3 there is no mode.

However in something like:
1,1,1,2,2,2,3 , the mode would be 1 and 2
