Good Arrays

CodeChefRating 2828Open on judge ↗

Chef considers an array *good* if it has no subarray of size less than $N$ such that the [GCD](https://en.wikipedia.org/wiki/Greatest_common_divisor) of all the elements of the subarray is **equal** to $1$. Chef has an array $A$ of size $N$ with him. He wants to convert it into a *good* array by applying a specific operation. In one operation, Chef can choose any subarray and **reverse** it.
