Is there a function in Julia that can generate a random integer in the range and without repeats?

Have you checked `?randperm` or `?shuffle`? Do they work for you?

I’m not sure what you mean by “in the range” but `rand(1:10)` gives you an integer between (and including) 1 and 10.

Sampling without replacement is probably what you are looking for. [http://juliastats.github.io/StatsBase.jl/stable/sampling.html#Sampling-from-Population-1](http://juliastats.github.io/StatsBase.jl/stable/sampling.html#Sampling-from-Population-1)
