Let us assume that the input data-structure is a matrix G[1..N;1..N]
of dimesion N*N matrix where G(i,j) = 1 if i !=j and i has won, 0
otherwise.
Note that the required sequence cannot contain 1 as 0th player does
not exists
Following algorithm may be used.
For i:=2 to N, do:
{
if ( ( G(i , i+1) = 0 ) AND (G( i , i-1) = 1) )
ouput i ;
}//End of for-loop.
Order of running time O(N).
