Display the given list of points in an orthonormal basis as an ASCII graph.
The X axis is represented by dash characters -. The Y axis is represented by vertical bar (pipe) characters |. The origin of the graph is represented by a plus character +. Every point of the given list is represented by a star character *. Every empty cell of the graph is represented by a dot character ..
If one of the given points is on an axis, the star character * must be chosen over the one corresponding to the axis.
The size of the graph to display is defined by the following rules: The minimal coordinate on the X axis is: (Minimal X axis coordinate of any given point and/or origin) - 1 The maximal coordinate on the X axis is: (Maximal X axis coordinate of any given point and/or origin) + 1 The minimal coordinate on the Y axis is: (Minimal Y axis coordinate of any given point and/or origin) - 1 The maximal coordinate on the Y axis is: (Maximal Y axis coordinate of any given point and/or origin) + 1
INPUT:
Line 1: An integer N, the number of points on the graph Next N lines: Two integers x and y, separated by a space, for the coordinates of every given points.
OUTPUT:
Strings, each one representing one ligne of the ASCII graph.
