1 reverse and insert [ 4, [ 0, [ ] ] ] to the beginning of [ 2, [ ] ] = reverse and insert [ 0, [ ] ] to the beginning of [ 4, [ 2, [ ] ] ] reverse and insert [ 4, [ 0, [ ] ] ] to the beginning of [ 2, [ ] ] = reverse and insert [ 0, [ ] ] to the beginning of [ 4, [ 2, [ ] ] ]
2 reverse and insert [ 0, [ ] ] to the beginning of [ 4, [ 2, [ ] ] ] = reverse and insert [ ] to the beginning of [ 0, [ 4, [ 2, [ ] ] ] ] reverse and insert [ 0, [ ] ] to the beginning of [ 4, [ 2, [ ] ] ] = reverse and insert [ ] to the beginning of [ 0, [ 4, [ 2, [ ] ] ] ]
3 reverse and insert [ ] to the beginning of [ 0, [ 4, [ 2, [ ] ] ] ] = [ 0, [ 4, [ 2, [ ] ] ] ] reverse and insert [ ] to the beginning of [ 0, [ 4, [ 2, [ ] ] ] ] = [ 0, [ 4, [ 2, [ ] ] ] ]
4 reverse and insert [ 4, [ 0, [ ] ] ] to the beginning of [ 2, [ ] ] = reverse and insert [ ] to the beginning of [ 0, [ 4, [ 2, [ ] ] ] ] if reverse and insert [ 4, [ 0, [ ] ] ] to the beginning of [ 2, [ ] ] = reverse and insert [ 0, [ ] ] to the beginning of [ 4, [ 2, [ ] ] ] and reverse and insert [ 0, [ ] ] to the beginning of [ 4, [ 2, [ ] ] ] = reverse and insert [ ] to the beginning of [ 0, [ 4, [ 2, [ ] ] ] ], then reverse and insert [ 4, [ 0, [ ] ] ] to the beginning of [ 2, [ ] ] = reverse and insert [ ] to the beginning of [ 0, [ 4, [ 2, [ ] ] ] ]
5 reverse and insert [ 4, [ 0, [ ] ] ] to the beginning of [ 2, [ ] ] = [ 0, [ 4, [ 2, [ ] ] ] ] if reverse and insert [ 4, [ 0, [ ] ] ] to the beginning of [ 2, [ ] ] = reverse and insert [ ] to the beginning of [ 0, [ 4, [ 2, [ ] ] ] ] and reverse and insert [ ] to the beginning of [ 0, [ 4, [ 2, [ ] ] ] ] = [ 0, [ 4, [ 2, [ ] ] ] ], then reverse and insert [ 4, [ 0, [ ] ] ] to the beginning of [ 2, [ ] ] = [ 0, [ 4, [ 2, [ ] ] ] ]
