Unique strings v2

Same problem as Unique strings, but with 3 CPUs available and scoring based on wall time instead of CPU time.

Count the exact number of unique tokens as fast as possible.

Input

One token per line on STDIN:

Output

Print the exact count of unique tokens to STDOUT.

Constraints

Character set: 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ@#%*
Maximum token length: 16
Approximately 1,000,000 unique tokens
