Multiply two matrices

Statement

Given three positive integers

$m$ ,

$n$ and

$r$ ,

$m$ lines of

$n$ elements, giving an

$m \times n$ matrix

$A$ , and

$n$ lines of

$r$ elements, giving an

$n \times r$ matrix

$B$ , form the product matrix

$A B$ , which is the

$m \times r$ matrix whose

$(i,k)$ entry is the sum

$A[i][1] * B[1][k] + \cdots + A[i][n] * B[n][k]$ and print the result.
