there are N elements in an array. u have one number x. u have to check whether there exists two elements in that array whose sum is x. But order should be less than N^2( N square). i dont know the method how to achieve order less than n^2.

#define prn(a) printf("%d",a) #define print(a,b,c) prn(a), prn(b), prn(c) #define max(a,b) (a<b)? b:a main() { int x=1, y=2; print(max(x++,y),x,y); print(max(x++,y),x,y); } output:222342 pls explain how we get output 342 at end
