`~a` and `a + 1` are also negative of each other too:
```
int f(int a, int b)
{
int t = ~a;
int t1 = -t;
return t1 == t;
}
int f1(int a)
{
return (~a) == (-~a);
}
int f2(int a)
{
return (a) ==

The following patterns could be improved/removed while doing this:
```
/* (A - B) == 0 ? (A - B) : (B - A)same as (B - A) */
/* (A - B) != 0 ? (A - B) : (B - A)same as (A - B) */
/* (A - B) >=/>
