How I should use unreal algo function with TArray?

Hey! Tell me how to use the native library of algorithms in Unreal. Let’s say I have a sorted array of ints (TArray ) and I want to use the Algo :: LowerBound function. I don’t understand what RangeType is in this case.

Oh maybe you could help me undertanding how i can use unreal iterators working with standard library of algorithms such as std::lower_bound?!
