You are required to create a program, which simulates a chessboard and the movements of various types of pieces on the chessboard. Chessboard: The chessboard is an 8 x 8 grid with 64 cells in it. With 8 rows (A, B, C…. H) and 8 columns (1, 2, 3…. 8), each cell can be uniquely identified with its cell number. This can be seen illustrated below.

A8 B8 C8 D8 E8 F8 G8 H8
A7 B7 C7 D7 E7 F7 G7 H7
A6 B6 C6 D6 E6 F6 G6 H6
A5 B5 C5 D5 E5 F5 G5 H5
A4 B4 C4 D4 E4 F4 G4 H4
A3 B3 C3 D3 E3 F3 G3 H3
A2 B2 C2 D2 E2 F2 G2 H2
A1 B1 C1 D1 E1 F1 G1 H1

The game of chess has 6 unique types of pieces, with their own unique types of movements. These are

1.) King – Can move only 1 step at a time in all 8 directions (horizontal, vertical and diagonal)

2.) Queen – Can move across the board in all 8 directions

3.) Bishop – Can move across the board only diagonally

4.) Horse – Can move across the board only in 2.5 steps (2 vertical steps and 1 horizontal step)

5.) Rook – Can move across the board only vertically and horizontally

6.) Pawn – Can move only 1 step at a time, in the forward direction, vertically. Can also move 1 step forward diagonally, in order to eliminate an opposing piece.

Your program should simulate the movement of each unique chess piece on an empty chessboard.

• Input – The input string to your program will be the Type of chess piece and its Position (cell number) on the chessboard. E.g. “King D5”

• Output – Once you execute the program, the output will be a string of all possible cells in which the chess piece can move.

Input – “King D5”
Output – “D6, E6, E5, E4, D4, C4, C5, C6”

A3 B3 C3 D3 E3 F3 G3 H3
A2 B2 C2 D2 E2 F2 G2 H2
A1 B1 C1 D1 E1 F1 G1 H1


Input – “Horse E3”
Output – “F5, G4, G2, F1, D1, C2, C4, D5”
A8 B8 C8 D8 E8 F8 G8 H8
A7 B7 C7 D7 E7 F7 G7 H7
A6 B6 C6 D6 E6 F6 G6 H6
A5 B5 C5 D5 E5 F5 G5 H5

A3 B3 C3 D3 E3 F3 G3 H3
A2 B2 C2 D2 E2 F2 G2 H2
A1 B1 C1 D1 E1 F1 G1 H1

The program is written in golang, to run type command

go run main.go

TODO: Need to add testcases and make the code more moduler
