The problem is to write a program in 'C' to find the greatest
of 2 given numbers... Easy? huh
here's the catch
do not use 'if' or any conditional statements
if u want it to be a little more tougher you can use the if but
this time no relational operators or any of the predefined
functions....
Can someone please help me solve the problem....
I read a similar (but more restricted) question very recently
in another forum.
The following uses strtol() to convert arguments on the command
line, and printf() to output the maximum. Otherwise, it doesn't
use any conditional, logical, equality or relational operators,
nor does it use any selection or iteration statements.
Not sure if Google will mangle this...

q3))+1))-1)+q6;}q1 q7(long q8){return q2(q8,0,q2(q8/2,0,1
