	description: "ChestX-ray dataset comprises 112,120 frontal-view X-ray images of 30,805 unique patients with the text-mined fourteen disease image labels (where each image can have multi-labels), mined from the associated radiological reports using natural language processing. Fourteen common thoracic pathologies include Atelectasis, Consolidation, Infiltration, Pneumothorax, Edema, Emphysema, Fibrosis, Effusion, Pneumonia, Pleural_thickening, Cardiomegaly, Nodule, Mass and Hernia, which is an extension of the 8 common disease patterns listed in our CVPR2017 paper. Note that original radiology reports (associated with these chest x-ray studies) are not meant to be publicly shared for many reasons. The text-mined disease labels are expected to have accuracy >90%.Please find more details and benchmark performance of trained models based on 14 disease labels in our arxiv paper: 1705.02315"

强迫症老板和他的洗碗工

	"""
	强迫症老板和他的洗碗工（10分）
	题目内容：
	洗碗工小明碰上了一位强迫症老板老王，餐厅一共就10只盘子，
	老板给仔细编上了0～9等10个号码，并要求小明按照从0到9的编号来洗盘子，
	当然，每洗好一只盘子，就必须得整齐叠放起来。
	小明洗盘子期间，经常就有顾客来取盘子，当然每位顾客只能从盘子堆最上面取1只盘子离开。
	老王在收银台仔细地记录了顾客依次取到盘子的编号，比如“1043257689”，
	这样他就能判断小明是不是遵照命令按照0123456789的次序来洗盘子了。
	你也能像老王一样作出准确的判断吗？
