How to split text without repetition?

PHP

We need a function that parses the text into all combinations without repetition
. For example, like this
1) the boat swam swam and drowned
2) the boat swam swam and
3) swam swam and drowned
4) the boat swam swam
5) swam and drowned
6) the boat swam
7) swam swam
8) swam and
9) and drowned
10) boat
11) swam
12) and
13) drowned
Maybe I even missed it, I don’t know for sure

Answer 1

var start = ('кораблик плавал плавал и утонул').split(' ');

for (var i = 0, result = [], _result = {}, stroke; i <= start.length; i++) {
  for (var j = 0; j < i; j++) {
    stroke = start.slice(j, j + start.length - i + 1).join(' ');

    if (!_result[stroke]) {
      _result[stroke] = result.push(stroke);
    }
  }
}

console.log(result);
