Triplets Count
CodeChefOpen on judge ↗
You are given an array and you need to find number of tripets of indices **(i ,j, k)** such that the elements at those indices are in *geometric progression* for a given common ratio $r$ such that $i < j < k$. For example, given an array $arr = [1, 4, 16, 64]$ and $r = 4$, we only have $[1 ,4, 16]$ and $[4, 16, 64]$ at indices $(0, 1, 2)$ and $(1, 2, 3)$. Hence we print $2$. ### Input - T
