The Quest!

You are a blacksmith and calculate the strength of your weapons by its name!

Names can be anything you may image, example names might be..

The Quest!

Key notes

Write a function which takes one parameter, the weapon name as a string, and returns its strength!

Each word in the weapons name counts strength +3

Some words have a special meaning:

• tiny => strength +5
  • "Cute tiny hammer"
    = 3 + 5 + 3 = 11
• awesome => Multiplies strength of all prior words by 2
  • "Shining mace of awesome power"
    = (3 + 3 + 3) * 2 + 3 = 21

The Quest!

Extension

We add conditions to weapons, expressed by a word in braces at the end. There are three conditions.

• Perfect: Multiplies strength by 1.5
  • "Cute tiny hammer (Perfect)"
    = (3 + 5 + 3) * 1.5 = 16.5
• Normal: Changes nothing
• Flawed: Multiplies strength by 0.5
  • "Cute tiny hammer (Flawed)"
    = (3 + 5 + 3) * 0.5 = 5.5

Weapons without a specific condition are considered as normal!
