215. DS一个女生,在算TELEPHONE BILL的时候喜欢round to nearest 1 dollar, 问这女生最后评估的电话费是否在8dollar之内(这是我最后一道题,看最后的问题时理解了老半天,不知有没理解错,原句是“does she estimated the sum of her charge of telephone bill within 8$ of the sum of actual charge of telephone bill.”) 1)each of the bill is less than 7.75$ 2) 有14个BILL
B吧。。
118.DS X+Y>1否, X,Y是positive
1 X^2+Y^2>1
2 X^2-Y^2>1/2
这个也变体了。。可是我忘了。。。不好意思。。。
