Javascript K在线性时间内最接近原点？

function findKClosestPoints(points, K) {
  // 计算每个点到原点的距离
  const distances = points.map(point => {
    const distance = Math.sqrt(point[0] * point[0] + point[1] * point[1]);
    return { point, distance };
  });

  // 对距离进行排序
  distances.sort((a, b) => a.distance - b.distance);

  // 取前K个点作为结果
  const result = distances.slice(0, K).map(item => item.point);
  return result;
}

// 示例用法
const points = [[1, 2], [3, 4], [5, 6], [7, 8], [9, 10]];
const K = 3;
const closestPoints = findKClosestPoints(points, K);
console.log(closestPoints);
