Write a program, that input an odd number of integers. Each odd input is x coordinate, and each even input is y coordinate of a certain dot. If x is negative, input ends immediately and the program outputs 16×16 character matrix, containing '*' at places of the dots and '.' at empty places. The 0:0 coordinate is at upper-left corner (OX points right, OY points down).
