Here is my method for part of a calculator app, could someone take a
look and see why it isnt working?(PS is parenthases start while PE is
end)
Boolean solve2( int min, int max){
int x = min-1;
while(x<max)

x++;

if(Boolean.parseBoolean(note.getString(note.getColumnIndexOrThrow(NotesDbAdapter.KEY_ISPS))))
{
int y = x;
boolean z = false;
while(y<max && z==false){
y++;
Cursor note1 = mDbHelper.fetchNote(y);
if(Boolean.parseBoolean(note1.getString(note.getColumnIndexOrThrow(NotesDbAdapter.KEY_ISPE))))
{z = true;}
}
solve1(x,y);
max-=(y-x);
}}

Solve 1 is identical except it uses Solve 2 in the paranthasees
portion.
