i only want to keep the repetitions in a stream of numbers,

so if its like 46 42 36 36 36 36 42 i want to "isolate" 36 36 36 36

This works, but you may add a copy of the repeated number to the output, because i misses the first one before it gets that it's repeating.

Do you need all four 36s in the above example? If so, here's a slightly different take which compares it against two neighbors. (I've included Mike S's for comparison)

pretty hard to compare a number to the next number in a stream ^^

Yeah, there's a latency of one value, but you also correctly identify all values in the long run. Can't have it both ways...

With a simple modification to output the initial integer, Mike S.'s approach is almost twice as fast as the others..

(still have not looked at the patches though...as im trying to solve it in an easy way.:)

I stand corrected. Nice solution, Metamax.

@FlowDesigner Here's an encapsulated, drop-in ready version of Solution A (Mike S./Metamax).

yet another solution. Maybe not the most efficient, but with fewer objects:

opposite of change?
