I have the following vector:
[**17, 17**, 1954, 909, **17, 17**, 411, 844, **17, 17**, 1954, 909, **17, 17**, 411, 844]
-
As can be seen, the indices [0,1]; [4,5]; [8, 9] and [12, 13] are equal.
-
I need to assign a random value, but equal, to the indexes [8, 9] and [12, 13].
-
How do I create the logic needed for this situation? and future situations with larger vectors?
For example, the output vector should look like this:
[17, 17, 1954, 909, 17, 17, 411, 844, **23, 23**, 1954, 909, **23, 23**, 411, 844]
