PROGRAMMING:Output the product of two matrices

####Task description
```
Program to output the product of two matrices.
```
####Input format:
```
The first is three positive integers a, B, C (0 〈 a, B, C < 100), which means that the first matrix is row a and column B, and the second matrix is row B and column C.
Then there are a row of integers, B in each row, separated by spaces, representing the contents of the first matrix.
Then there are B-line integers, C in each line, separated by spaces, representing the contents of the second matrix.
```
####Output format:
```
Output the product of two matrices, as a row of integers, each row of C column, integers separated by a space.
```
