problem_description: Matrix Multiplication
  
    
  
  Write a program which reads a $n \times m$ matrix $A$ and a $m \times l$
  matrix $B$, and prints their product, a $n \times l$ matrix $C$. An element of
  matrix $C$ is obtained by the following formula:
  
  \\[ c_{ij} = \sum_{k=1}^m a_{ik}b_{kj} \\]
  
  where $a_{ij}$, $b_{ij}$ and $c_{ij}$ are elements of $A$, $B$ and $C$
  respectively.
