In this kata we accept as an input the number of rows and columns as our input and we have to return a multiplication table according to the given dimensions.

We declare an empty array as ans. We loop from 1 till the end of the given input row.For every iteration we declare an empty sub-array. Then we loop from 1 to the given input column and multiply the row and column and push the product to sub-array. After complete iteration of columns we push the sub-array to ans array and continue the iteration with next row.

In the end we return the ans array as the required multiplication table.
