[Verification and Validation]

The function is supposed to find the maximum of the row-wise minimum values of the integers in the given 2D-array , i.e.

The function should return -1 if the given array is empty or in case all rows in the array are empty. The program below contains an implementation of this function.

1) Draw a control flow graph for the program above.

2) Find a test suite which satisfies a highest degree of edge coverage on the graph given in 1).
