簡單

Ha, saw this question somewhere, what's the following number?

1
11
21
1211
3112
211312

?

You don't need a math degree to solve it. The answer is more simple than you can think.

Seems like the run-length encoding (RLE) data compression algorithm ;)

哈﹐不懂數學的人"數"對了。起初我也是想得一頭霧水﹐原來卻是幼稚園也懂的數數目字﹐"one", "one one", "two one", "one two, one one", "three one, one two", "two one, one three, one two"﹐ 故此bwd原全正確。想得複雜反而解不開。

嘻﹐用compression algorithm 當然也絕對準確﹐不過有點小題大做了。哈﹐因為這條真的是幼稚園題目。
