I do apologise for my vague question. I am a beginner when it comes to programming so mainly I follow tutorials, however I was not able to find something similar to what I want. I have around 300,000 numbers and I want to randomly change around 500 numbers at a time, either adding a +1 or -1 to that number without changing the structure of the numbers.
