1 2 3<H1>Advanced Algorithm Class</H1>4 5<p>6   In the advanced algorithm class, n<sup>2</sup> students sit in n rows and7n columns. One day, a professor who teaches this subject comes into the class, asks the shortest student in each row to lift up his left hand, and the tallest student in each column to lift up his right hand.8What is the height of the student whose both hands are up ? The student will9become a target for professor’s questions.10</p>11<p>12   Given the size of the class, and the height of the students in the class, you13have to print the height of the student who has both his hands up in the class.14</p>15 16<H2>Input</H2>17 18<p>19The input will consist of several cases. the first line of each case will be n(0 < n < 100), the number of rows and columns in the class. It will then20be followed by a n-by-n matrix, each row of the matrix appearing on a single21line. Note that the elements of the matrix may not be necessarily distinct. The22input will be terminated by the case n = 0.23 24</p>25 26<H2>Output</H2>27 28<p>29For each input case, you have to print the height of the student in the class30whose both hands are up.
