the chellenge is simplify such quicksort code as far as you can
conditions
1) it should work proper way
2) should be not slower or only slightly slower
(so thsi is not optimistation for speed its more for being simple but
staing reasonably fast)
3) by simplify i mean maybe removing soem if or some other
element but not necassary rewriting names for shorter etc as names are
not much meaningfull here (so by simplifying i mainy understand
removing something or some recomposition for something better/clearer)
4) the basic quicksort has two calls inside this one is
opitmised to have only one , i think both versions are okay
but maybe thsi one with one call inside is maybe better
void QuicksortInts7(int* table, int lo, int hi)
{
int i=lo; int j=hi;
while (i<hi)
{
int pivot =table[(lo+hi)/2];
while (i<=j) // Partition
{
while (table[i]<pivot) i++;
while (table[j]>pivot) j--;
if (i<=j)
{
int t=table[i];table[i]=table[j];table[j]=t;
i++; j--;
}
}
if (lo < j){ QuicksortInts7(table, lo, j);} //recursion
lo=i; j=hi;
}
}
is there a way to simplify this?
