We’ll use the following pattern to count ships:
Solution:
let field = [
'xxx x ',
' x ',
'x ',
'x x ',
' x x',
' x x',
' ',
'x xxxx',
' ',
' xx x'
]
let ship_counter = 0
for (let i = 0; i < 10; i++) for (let j = 0; j < 10; j++)
if (field[i][j] === 'x' &&
(i === 0 || field[i-1][j] === ' ') &&
(j === 0 || field[i][j-1] === ' ')) ship_counter++
console.log('ship_counter = ', ship_counter)
