P9177 [COCI 2022/2023 #5] Kalendar

Magdalena likes calendars, and she makes her own calendar for each month. Each day of the month is represented using exactly three characters: - If the day number has one digit, it is written as `..X`. For example, the number $7$ is written as `..7`. - If the day number has two digits, it is written as `.XY`. For example, the number $17$ is written as `.17`. Each row of the calendar represents one week, and each week has $7$ days. If a week does not contain all $7$ days (because the month may not start on Monday, or may not end on Sunday), then the missing days are shown as `...`. Magdalena also wants her calendar to look nice. She will decorate it in the following way: she will fill the top and bottom with `-` (ASCII 45), the left and right sides with `|` (ASCII 124), and the four corners with `+` (ASCII 43). Your task is to determine the format of Magdalena's calendar if it has $n$ days and the first day of the month is the $x$-th day of the week. For example, if $x=1$, the month starts on Monday; if $x=5$, it starts on Friday. We assume that the first day of the week is Monday.

One line containing integers $n$ and $x(1\leq n\leq 99,1\leq x\leq 7)$, representing the number of days in the month and the weekday on which the month starts.

Output what Magdalena's calendar looks like.
