The first no. is 1
2 j# ]; \" b- h5 v" u5.39.217.77:8898The  next one describe it: there is only one "1", therefore 11公仔箱論壇0 @* P- p, I8 m3 U/ M+ w; \
The next one describe the "11" as there are two "1", therefore 21
+ j6 O  N( H# Y: DThe next one describe the "21" as there are one "2" and one "1", therefore 1211
