Hi, I have a flow that can find missing number in Array list.
But it's use many API calls (Can exceed API usage) and took long time to run (20~30 minutes).
Below is my flow figure :

I use "Do Until" step to lookup missing number in array.
1) Define 1st Number (eg : 12700) ---> 1st number in array
2) Do the increment (eg : 12701)
3) Search the number (12701) in the list of Array
4) Condition (If not found run certain steps. Else, search the next number)
Each run, estimated looping is around 1100~1700 times.
Is there's any way to simplify this method?
