Features

Generate ship layout

Example request:

curl -i http://localhost:8080/generate

Output:

{{7 4} {7 4}}
{{5 4} {5 4}}
{{6 1} {6 1}}
{{4 0} {4 0}}
{{1 3} {2 3}}
{{9 1} {9 2}}
{{2 6} {3 6}}
{{0 8} {2 8}}
{{6 6} {8 6}}
{{5 8} {8 8}}

Those are ship coordinates, e.g. last ship is on squares {5 8}, {6 8}, {7 8}, {8 8}

Generate ship layout as grid

Example request:

curl -i http://localhost:8080/generate/grid

Output:

oo#oo###o#
ooooooooo#
#oo#o#oooo
ooo#o#oo#o
ooo#oooooo
o#o#oooooo
o#oooooooo
o#ooo##ooo
oooooooooo
ooo#oooooo

o means the square is empty, # means there is a ship

Generate ship layout as image

Example request:

curl -i http://localhost:8080/generate/image

Output:

Validate ship layout

Example request:

curl -i http://localhost:8080/validate -d "{{7 5} {7 5}}
{{2 7} {2 7}}
{{2 3} {2 3}}
{{0 5} {0 5}}
{{6 2} {7 2}}
{{3 9} {4 9}}
{{9 3} {9 4}}
{{4 1} {4 3}}
{{6 8} {8 8}}
{{2 5} {5 5}}"

Output:

true

If layout is not valid (try to remove 1 ship) it would output false

You can use different format:

curl -i http://localhost:8080/validate -d "#ooooooooo
#o#oooo#oo
oooo#oo#o#
ooooooo#o#
#oooo#oooo
#ooooooo#o
#ooooooo#o
#o#ooooo#o
oo#oo#oooo
oooooooooo"

Output:

true

curl -i http://localhost:8080/replay -d "{{7 5} {7 5}}
{{2 7} {2 7}}
{{2 3} {2 3}}
{{0 5} {0 5}}
{{6 2} {7 2}}
{{3 9} {4 9}}
{{9 3} {9 4}}
