Op. 2, Variations, complete
As in the entire Variations, while writing A Chopin treated accidentals almost like key signature accidentals – he considered them to be valid in all octaves on a given stave and in a given clef. Therefore, in the R.H. part the last entered accidental is a to d1, while in the L.H. part it is the sharps to D, f and all starting from d2 that are missing. All necessary accidentals – assuming that they are also valid for notes at the same pitch under the octave sign – were added already in GE (→FE,EE, in the latter the notes under the octave sign were also provided with accidentals).
