Calculate Total Cost for Book Purchases

You are given the number of books purchased and whether the purchase was made on a weekend. The pricing scheme is defined as follows:

• If \(1 \leq n \leq 3\): each book costs $12.
• If \(4 \leq n \leq 6\): each book costs $10.
• If \(n \geq 7\): each book costs $8.

If the purchase is made on a weekend, a discount of 10% is applied to the total cost. In mathematical terms, if \(n\) is the number of books and the price per book is \(p\), then the total cost \(C\) is:

\[ C = \begin{cases} 0 & \text{if } n \leq 0,\\[1mm] n \times p & \text{if not weekend},\\[1mm] 0.9 \times n \times p & \text{if weekend.} \end{cases} \]

Your task is to implement a solution that reads the number of books and a boolean flag indicating if it is a weekend, and then outputs the calculated total cost based on the above conditions.

inputFormat

The input is provided via standard input (stdin) and consists of two lines:

• The first line contains an integer representing the number of books purchased.
• The second line contains a string (True or False) indicating whether the purchase was made on a weekend.

outputFormat

The output should be printed to standard output (stdout) and is the total cost after applying the pricing scheme and any weekend discount. If the computed cost is a whole number, output it as an integer; otherwise, output the decimal value.
