# Problem: Flowers Shop

A flowers shop offers 3 types of flowers: **chrysanthemums**, **roses** and **tulips**. The prices depend on the season.

Season | Chrysanthemums | Roses | Tulips |
---|---|---|---|

spring / summer autumn / winter |
2.00 USD/pc 3.75 USD/pc |
4.10 USD/pc 4.50 USD/pc |
2.50 USD/pc 4.15 USD/pc |

On holidays, prices of all flowers are **increased by 15%.** The following **discounts** are offered:

- For purchasing more than 7 tulips in spring –
**5% of the price**of the whole bouquet. - For purchasing 10 or more roses in winter –
**10% of the price**of the whole bouquet. - For purchasing more than 20 flowers in total in any season –
**20% of the price**of the whole bouquet.

**Discounts are made in the above described order and can be combined! All discounts are valid after increasing of the price on a holiday!**

The price for arranging a bouquet is always **2 USD**. Write a program that calculates the **price of a bouquet**.

## Input Data

The input is read from the **console** and contains **exactly 5 lines**:

- The first line contains
**the number of purchased chrysanthemums**– an integer within the range [**0 … 200**]. - The second line contains
**the number of purchased roses**– an integer within the range [**0 … 200**]. - The third line contains
**the number of purchased tulips**– an integer within the range [**0 … 200**]. - The fourth line indicates
**the season**– [**Spring, Summer, Autumn, Winter**]. - The fifth line specifies
**if the day is a holiday**– [**Y = yes / N = no**].

## Output Data

Print on the console 1 number – **the price of flowers**, formatted up to the second symbol after the decimal point.

## Sample Input and Output

Input | Output | Comments |
---|---|---|

2 4 8 Spring Y |
46.14 | Price: 2*2.00 + 4*4.10 + 8*2.50 = 40.40 USD |

**Holiday**: 40.40 + 15% = 46.46 USD

**5% discount** for more than 7 tulips in spring: 44.14

The flowers are in total 20 or less: **no discount**

44.14 + 2 **for arranging the bouquet** = 46.14 USD|

Input | Output | Comments |
---|---|---|

3 10 9 Winter N |
69.39 | Price: 3*3.75 + 10*4.50 + 9*4.15 = 93.60 USD |

**Not a holiday**: no increase in price**10% discount** for 10 or more roses in winter: 84.24

The flowers are in total over 20: **20% discount** = 67.392

67.392 + 2 **for arranging the bouquet** = 69.392 USD|

Input | Output |
---|---|

10 10 10 Autumn N |
101.20 |

## Hints and Guidelines

We will divide the problem into smaller sub-problems, as described below.

### Separating the Constant Values in Variables

After carefully reading the requirements, we understand that once again we need to do **simple calculations**, however this time we will need **additional** logical **conditions**. We need to pay more **attention** to the moment of **making changes** in the final price, in order to be able to properly build the logic of our program. Again, the bold text gives us sufficient **guidelines** on how to proceed. For a start, we will separate the already **defined** values in **variables**, like we did in the previous tasks:

We will also do the same for the rest of the defined values:

### Reading the Input Data

Our next sub-task is to **read** properly **the input** data from the console. We will do that in the familiar way, but this time we will **combine two** separate functions – one for **reading** a line from the console and another one for its **conversion** into a numeric data type:

### Preparing the Program Logic

Let's think of the most appropriate way to **structure** our programming logic. By the requirements it becomes clear that the path of the program is divided mainly into two parts: **spring / summer** and **autumn / winter**. We can do the separation by conditional statement, by storing variables in advance for the **prices** of the individual flowers, as well as for the **end result**.

What remains is to perform **a few checks** regarding **the discounts** of the different types of flowers, depending on the season, and to modify the end result.
