it would start with 4 billion v.s. 4 billion.

then it would narrow down to 2 billion v.s. 2 billion.

then it would go down to 1 billion v.s. 1 billion.

then i would go down to 500 million v.s. 500 million.

then it would go down to 250 million v.s. 250 million.

Then it would go down to 125 million v.s. 125 million.

then it would go down to 62,500 v.s 62,500.

then it would go down to 31,250 v.s. 31,250.

then it would go down to 15,625 v.s. 15,625.

then it would go down to 7,812 v.s. 7812.

then it would go down to 3,906 v.s. 3906.

then it would go down to 1,953 v.s. 1953.

then it would go down to 976 v.s. 976.

then it would go down to 488 v.s. 488.

then it would go down to 244 v.s. 244.

then it would go down to 122 v.s. 122.

then it would go down to 61 v.s. 61.

then it would go down to 30 v.s. 30.

then it would go down to 15 vs 15.

then it would go down to 7 vs 7.

then it would go down to 3 vs 3.

then it would go down to 1 vs 1.

so it would take 22 matches if the matches were conducted like tournements.
