if we have these inputs e.g. {11, 3, 9, 7, 4)Code:/* qsort: sort v[left]...v[right] into increasing order */ void qsort(int v[], int left, int right) { int i, last; void swap(int v[], int i, int j); if (left >= right) /* do nothing if array contains */ return; /* fewer than two elements */ swap(v, left, (left + right)/2); /* move partition elem */ last = left; /* to v[0] */ for (i = left + 1; i <= right; i++) /* partition */ if (v[i] < v[left]) swap(v, ++last, i); swap(v, left, last); /* restore partition elem */ qsort(v, left, last-1); qsort(v, last+1, right); }

Just a bit... so that I can proceed!
