Problem 3026. Legend of Zelda - Rupee Count (Compact)

Building off of Problem 3025, suppose that Link's rupee wallet will now provide a compact string with one letter designating each rupee he's picked up. Once again, the rupee denominations are (with abbreviating characters):

• Green (g) = 1
• Blue (b) = 5
• Yellow (y) = 10
• Red (r) = 20
• Purple (p) = 50
• Orange (o) = 100
• Silver (s) = 200
• Big green (G) = 50
• Big blue (B) = 100
• Big red (R) = 200
• Big gold (*) = 300

Note that the string will be case-sensitive. Write a function to return the total value of rupees that Link has accumulated provided the compact rupee string.
