I am writing a big C code...
The code includes recursive bactracking function named Branch() that is called so much...
My goal is to write the fastest code to get the best running time...

I also have another function Redundant()

void Redundant()
{
 int* A;
 A=(int*)malloc(100*sizeof(int));
}

I created two versions.
Version A: Redundant() is included in Branch().
Version B: Redundant() is not included in Branch()

A run 10 times faster than B !!!!

Is is Magic or is it kind of process scheduling or what ??
