如何从一个数组中找到最远的3个连续元素

function findFarthestThreeElements(arr) {
  let start = 0;
  let end = 0;

  for (let i = 0; i < arr.length - 2; i++) {
    const currentStart = i;
    const currentEnd = i + 2;

    if (currentEnd - currentStart > end - start) {
      start = currentStart;
      end = currentEnd;
    }
  }

  return arr.slice(start, end + 1);
}

const array = [1, 2, 3, 4, 5, 6, 7, 8, 9];
const farthestThreeElements = findFarthestThreeElements(array);
console.log(farthestThreeElements);  // 输出 [7, 8, 9]
