Why?

Software
Crisis

The major cause of the
software crisis is that the machines have become several orders of magnitude more powerful! To put it quite bluntly: as long as there were no machines, programming was no problem at all…

…When we had a few
weak computers, programming became a mild problem, and now we have gigantic computers, programming has become an equally gigantic problem. Edsger W. Dijkstra

void quick_sort (int *a, int
n) { if (n < 2) return; int p = a[n / 2]; int *l = a; int *r = a + n - 1; while (l <= r) { if (*l < p) { l++; } else if (*r > p) { r--; } else { int t = *l; *l = *r; *r = t; l++; r--; } } quick_sort(a, r - a + 1); quick_sort(l, a + n - l); }

qsort :: Ord a =>
[a] -> [a] qsort [] = [] qsort (x:xs) = qsort less ++ [x] ++ qsort greater where less = [ y | y <- xs, y < x ] greater = [ y | y <- xs, y >= x ]
