Assumptions: • Each row is sorted in ascending order Each column is sorted in ascending order In what follows, we will call a matrix any matrix that satisfies the conditions shown in the image above. We will addittionally assume, that the matrix may have missing numerical ele- ments. In this case, the cell fill be filled with the special value INF which is larger than any number (like infinity in mathematics). If a row contains an INF value this must be the last value, and if a column contains an INF value this must be the last value as well. For example, if a matrix contains a single INF value (and the rest is filled with numbers) the INF value must be located in the bottom row of the right- most column.
