Input: Sketch of the outline of the buildings in a matrix.
Output: The column number of the highest building and height of it. In two or more building are the highest, you need to choose the first one.
Example:
Let us consider buildings described by the matrix
M=[0 0 1 0;
1 0 1 1;
1 1 1 1;
1 1 1 1]
  • The height of the first building (1st column) is 3,
  • the height of the second building (2nd column) is 2,
