# Divide every element of one array by other array elements

Given two arrays and the operation to be performed is that the every element of a[] should be divided by all the element of b[] and their floor value has to be calculated.

Examples :

```Input : a[] = {5, 100, 8}, b[] = {2, 3}
Output : 0 16 1
Explanation :
Size of a[] is 3.
Size of b[] is 2.
Now 5 has to be divided by the elements of array b[]
i.e. 5 is divided by 2, then the quotient obtained
is divided by 3 and the floor value of this is
calculated. The same process is repeated for the other
array elements.
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

First Approach : This solution is of complexity O(n * m) where size of a[] is n and size of array b[] is m. In this solution we fix the elements of array a[] and iterate it with the elements of array b[].

Second Approach : In this method we have used simple maths. We first find product of array B and then divide it by each array element of a[]
The complexity of this solution is O(n).
