Task $1$: Displaying the Game Board

In this task you will develop a program to display to the screen a text$-$based representation of the state of the board mid$-$way through a game of Graze. Your program will take as an input argument a string of characters that represent the current state of each square of the board.

Implementation details

Board Coordinates

To facilitate in a computer$-$based version of Graze in a terminal environment, a set of coordinates can be setup to represent the different playing positions on the board. The board rows are represented by numbers $0,1,2,3,$ and columns by the letters a$,$b$,$c$,$d:

Using this system, player $1\text{'}$s first move above would be $\text{'}1$b$\text{'},$ and player $2\text{'}$s first move would be $\text{'}2$c$\text{'}.$

Displaying the board:

You program should display the current state of the board using printf statements in the following form:

abcd

$0**$

$1****$

$2****$

$3**$

where the "abcd" indicate the board columns, $"0123"$ indicate the board rows, and $"*"$ represents playable$/$empty board positions. Any board positions that are occupied by player $1$ or player $2\text{'}$s tokens should be indicated by the symbols $"$X$"($for player $1)$ and $"$O$"($for player $2).$ For example, the board position:

Would be printed to the screen as:

abcd

$0*$X

$1*$X$**$

$2$ O$*$OO

$3$ X$*$

Program Input

Your program should run with the following format:

$./$display$\_$graze$\_$board

where is a $12-$character long string that indicates the board state, represented by numbers, where $0$ represents an empty square, $1$ represents one of player $1\text{'}$s tokens, and $2$ represents one of player $2\text{'}$s tokens. The string should provide the characters in the order: $0$b$,0$c$,1$a$,1$b$,1$c$,1$d$,2$a$,2$b$,2$c$,2$d$,3$b$,3$c $($i$.$e$.$ row$-$by$-$row, top to bottom$)$ e$.$g$.$:

$./$display$\_$graze$\_$board $000101202002$

should produce the output board:

abcd

$0**$

$1*$X$*$X

$2$ O$*$O$*$

$3*$O

For Task $1,$ you can assume that the input string will be provided without errors $($i$.$e$.$ automated test cases will always provide valid board state strings$),$ however you might like to run some simple error checking within your code.
