data = init(sizeOfInterval*4)

As an AI language model, I don't have enough context to understand the purpose of the "data = init(sizeOfInterval*4)" statement. However, I can make some assumptions based on common programming practices.

It seems that "init" is a function or method that initializes the "data" variable with some value or values. The value being assigned to "data" is the result of calling "init" with an argument of "sizeOfInterval*4".

The expression "sizeOfInterval*4" suggests that the size of the interval may be related to the amount of data being initialized. Perhaps "data" is an array or collection of some sort, and the size of the interval determines the number of elements in the array.

Without more context, it's difficult to say for certain what this statement does or why it's necessary.
