Swimming Fish Distance Calculation

A little fish swims 250 km on each weekday, while it rests on weekends (Saturday and Sunday). Given a starting day of the week x (where Monday is 1, Tuesday is 2, ..., Sunday is 7) and n consecutive days, compute the total distance the fish has swum after n days.

For example, if x=1 (Monday) and n=7, then the fish swims on Monday to Friday and rests on Saturday and Sunday, yielding a total of 5 * 250 = 1250 km.

The formula is: \( \text{Total Distance} = 250 \times (\text{number of weekdays in n days starting from day } x) \).

inputFormat

The input contains two integers x and n separated by a space:

• x: an integer (1 ≤ x ≤ 7) representing the starting day of the week (1 for Monday, 7 for Sunday)
• n: the number of days

outputFormat

Output a single integer representing the total kilometers swum by the fish after n days.
