I have couple of question:
1 - Why the `word` cannot represented by `1w11` or `22`, I maybe have completed misunderstood the question? Will appreciate your answers 2 - Why are using `1 2 3 4` here to abbreviate a word? 3 - Generally if you have a sentence like `talk to you later -> ttyl` or `for your information -> fyi`, we use the first letter from sentence? Aren't we doing something similar here?
Question may sound dumb but well I am not able to understand it. Will appreciate any help! Thank you
It's the kind of abbreviation where a number stands for that many letters. For example, your "1w11" would mean one letter followed by "w" followed by eleven more letters. So for example "swordsmanship".
A common example is "i18n".
I guess one number cannot followed by another number unless the number counts exceeds 10. The number of counts may stand for the number of letters which are replaced by such a number. ie. when the number comes to 4, the word "under" has only two abbreviations -- 4r and u4. You may not consider 41 or 14 as an abbreviation. (May not be appropriate plz correct me if I'm wrong.)
Just consider it as a game of permutation and combination.
I don't think they are the same.
