Identifying the index of a repeated element in an array [message #94520]

Hello everybody,

I have an array that looks like this:
x = [1,2,3,4,5,0,1,2,0,0,0,0,1,2,3,0,0,0,1,2,3]
I am interested in the location of the element "5" (index 4), "3" (index 14), and "3" (index 20).
I am writing a program to output the above three indices.
However, using min(where(x eq 3)) keeps giving me the index of the first 3, which I do not want.
I need the index of the second 3, and the third 3.

Is there any way to do this?

Thank you so much!
