function missingNumber(nums) {
  const n = nums.length;
  const expectedSum = (n * (n + 1)) / 2;
  const actualSum = nums.reduce((sum, num) => sum + num, 0);
  return expectedSum - actualSum;
}

// 測試範例
console.log(missingNumber([3, 0, 1]));  // 輸出: 2
console.log(missingNumber([0, 1]));     // 輸出: 2
console.log(missingNumber([9, 6, 4, 2, 3, 5, 7, 0, 1]));  // 輸出: 8
