Part of you is always traveling faster, always traveling ahead. Even when you are moving, it is never fast enough to satisfy that part of you... You have heard of other travelers whose maps are breadcrumbs, whose maps are stones, whose maps are the four winds, whose maps are yellow bricks laid one after the other. You read your map with your foot, and behind you somewhere there must be another traveler whose map is the bloody footprints that you are leaving behind you.

There is a map of fine white scars on the soles of your feet that tells you where you have been.''

##### >GET THE MOST INTENSE K ISOTOPOLOGUES FROM A CHEMICAL FORMULA

./neutronstar Sn10Xe20Nd30Dy40 10000 1.05 generates the 10000 most abundant isotope peaks of a molecule with 10 tin atoms, 20 xenon atoms, 30 neodymium atoms, and 40 dysprosium atoms.

The 1.05 is the rank of the layer-ordered heaps.

Layer-ordered heaps (LOHs) are an innovative way to get some benefits of sorting without the $$\Omega(n \log(n))$$ runtime. For example, the list [3,6,2,4,7,1,6] can be sorted to yield [1,2,3,4,6,6,7].
With $$\alpha=2,$$ we can create a layer-ordering such as [1],[3,2],[6,7,6,4]. That is, the sizes of each subsequent layer doubles asymptotically and every element in layer $$L_i$$ has $$L_i\leq L_{i+1};$$ however, unlike sorting, elements within a layer remain unordered.
An LOH of rank $$\alpha=2$$ can be constructed in $$O(n)$$ time by using linear 1D selection.
