本文介绍了一种方法，通过仅保留字符串的首尾字符，并用数字表示中间部分的长度，来简洁地表示原始字符串。这种方法不仅节省了空间，还能在特定场景下提高数据处理效率。通过实例演示了如何实现这一转换过程，并讨论了其应用范围。

一个string只保留首尾字母, 中间字母数用数字表示, 比如 “abcde” = “a3e”, “ab” = “ab”, “abc” = “a1c” . 给一组string, 输出相同abbreviation的所有string, 但重复的string不算.

abv_string = StringBuilder.append(charAt[0]), StringBuilder.append(str.length-2), StringBuilder.append(charAt[str.length]),
HashMap storing String abreviated_string, hashset of the real strings
output the set
