Enter some blockdata: Now is the time for scientists to educate all.
Our example random seed string is: HFG0UDE4

Concatenated with the "data": Now is the time for scientists to educate all.HFG0UDE4

Number will be between 0000 (0) and FFFF (65535)

0x0000 = 0
0xFFFF = 65535

Hash is: AC9FEA95C9D521272A0872144BB7F80210AEC36DDF1B3A10A417D0D03C86F56E
First 16 bits in Hex and Decimal: AC9F and 44191
44191 is not less than 20,000 so we did not solve the puzzle
