Lets say first player is the best player and he will win all the matches, now assume he plays match against all others and defeat them, thus a total of 31 matches will be required for him to do so.
Lets say we first have 16 matches, it will eliminate 16 persons.
Next we have 8 matches it will further eliminate 8 persons, leaving with us 8.
Next we again have 4 matches, leaving 4 persons.
Next 2 matches, leaving two finalists, and 1 match in finalist will decide the winner.
Thus a total of 16+8+4+2+1 = 31 matches will be needed to declare the winner.
