Jetbrains Academy - Minesweeper

My solutions for the Jetbrains Academy Problem Minesweeper

https://hyperskill.org/projects/8

The solution is build up step by step over several stages. Stage 1 is the first and simple one. The following stages build up on the previous stages and get more and more advanced. There are five stages in total.

Because each stage is completely independent of the previous one, IntelliJ might show some warnings about duplicated code between the stages.

Stage 1

We just print the field with some mines set.

just execute this:

gradle -PmainClass=stage1.MainKt run --console=plain

Stage 2

click here to see description @ JetBrains Academy

We ask the user for a number of mines and create a field with mines placed randomly.

just execute this:

gradle -PmainClass=stage2.MainKt run --console=plain

How many mines do you want on the field? 20
....X.XX.
.....X...
.X.......
....XX..X
.X.....X.
.XX...X..
..X..X..X
.X...X.X.
........X

Stage 3

We create a field with randomly placed mines and set counters in all adjacent cells.

just execute this:

gradle -PmainClass=stage3.MainKt run --console=plain

How many mines do you want on the field? 15
.......1X
1211...11
X3X1.....
3X31.1121
3X2..1X3X
X21..113X
342211.11
XXX3X2...
3X33X2...

Stage 4

click here to see description @ JetBrains Academy

We create a field with randomly placed mines, set the counters, hide the mines and let the user place markers.

just execute this:

gradle -PmainClass=stage4.MainKt run --console=plain

How many mines do you want on the field? 15
