Description

Accounting for computer machinists (ACM) have sufferred from the Y2K bugs and lost some vital data for preparing annual repo RT for MS Inc.All-what they remember are that Ms Inc. posted a surplus or a deficit each month's 1999 and each month when MS Inc posted Surplus, the amount of surplus is s and each month when MS Inc. posted deficit, the deficit was d. They does not remember which or how many months posted surplus or deficit. MS INC, unlike other companies, posts their earnings for each consecutive 5 months during a year. ACM knows that each of the these 8 postings reported a deficit but they does not know how much. The chief accountant is almost sure that MS Inc. was on to post surplus for the entire year of 1999. Almost but not quite.
Write a program, which decides whether MS Inc. suffered a deficit during 1999, or if a surplus for 1999 is possible, what is the maximum amount of surplus that they can post.

Input

Input is a sequence of lines, each containing and positive integers s and d.

Output

For each line of input, output one line containing either a single integer giving the amount of surplus for the entire yea R, or output deficit if it is impossible.

Sample Input

Waterloo local 2000.01.29 problem can not understand is flawed, also always thought every month surplus, deficit not the same; Orz (the most owed is here, like also reported a P AH) posts their earnings for each Consecutive 5 months during a year this sentence understanding: every 5 months means 1 ~ 5, 2 ~ 6, 3 ~ 7 ... 8 ~ Orz This also explains that there are 8 sheets for Mao.
