如何在对整数输入进行排序时在输出中显示"subject“

def sort_integers_with_subject(nums):
    n = len(nums)
    for i in range(n):
        for j in range(0, n-i-1):
            if nums[j] > nums[j+1]:
                nums[j], nums[j+1] = nums[j+1], nums[j]
    sorted_nums = []
    for num in nums:
        sorted_nums.append("subject")
        sorted_nums.append(num)
    return sorted_nums

# 示例输入
input_nums = [4, 2, 1, 3]

# 调用函数进行排序并输出结果
sorted_nums = sort_integers_with_subject(input_nums)
print(sorted_nums)
