Problem Statement |
| | A group of people stand before you arranged in rows and columns. Looking from above, they form an R by C rectangle of people. You will be given a String[] people containing the height of each person. Elements of people correspond to rows in the rectangle. Each element contains a space-delimited list of integers representing the heights of the people in that row. Your job is to return 2 specific heights in a int[]. The first is computed by finding the shortest person in each row, and then finding the tallest person among them (the "tallest-of-the-shortest"). The second is computed by finding the tallest person in each column, and then finding the shortest person among them (the "shortest-of-the-tallest"). |

Constraints |
| - | people will contain between 2 and 50 elements inclusive. |
| - | Each element of people will contain between 3 and 50 characters inclusive. |
| - | Each element of people will be a single space-delimited list of positive integers such that:
1) Each positive integer is between 1 and 1000 inclusive with no extra leading zeros.
2) Each element contains the same number of integers.
3) Each element contains at least 2 positive integers.
4) Each element does not contain leading or trailing whitespace. |

Examples |
| 0) | |
| | | Returns: { 4, 7 } | | The heights 2 and 4 are the shortest from the rows, so 4 is the taller of the two. The heights 9, 8, and 7 are the tallest from the columns, so 7 is the shortest of the 3. |
