K = Diff(i,j) not max

K = Diff(i,j) should be the difference not Max consider i = 19 and j = 20

let K = max (i,j)
min value of x such that 2^x >= K > 2^(x-1).
in xth level they will face each other.

how can we arrange the matches if n is odd?

a=min(i,j)
b=max(i,j)
if(a is even):{a=a-1}
if(b is odd):{b=b+1}
answer=ceil(log(b-a+1))
