qqf"wlguwwl.wl.<CR>q7@q5Gfl~ZZ

第一次尝试

感觉有点麻烦，尤其是第 5 行有个例外。

qq0f"wlguwwl.wl.jq7@q5Gfl~ZZ

28 分，差 7 分。

第二次尝试

稍微优化一下。

qqf"wlguwwl.wl.<CR>q7@q5Gfl~ZZ

27 分，差 6 分。

第三次尝试

看来得把 5 行的例外处理好。替换试试。

:%s/\u\zs\u*\ze[- "]/\L&/g<CR>ZZ

29 分，还多了。

第四次尝试

直接看吧。

@rocker_zzy

qqf"llguwEbl.wl.wl.<CR>q7@qZZ

26 分。重点是 Ebl，这个专门处理第 5 行的例外。那可以再简化成 Eh，改造下。

qqf"wlguwEh.wl.wl.<CR>q7@qZZ

25 分，还差 4 分。

第五次尝试

想不出来还能怎么优化了。

qqvi"uvUf"b.b.+q7@qZZ

21 分。这思路果然不同凡响，先全转换成小写，然后从后往前依次把第一个字母转换成大写，巧妙处理了第 5 行的例外。
