化简叠词

代码如下：

import org.junit.Test;public class ReduplicatedWords {/* * 化简叠词：如aaabccd,化简为a3bc2d */@Testpublic void reduplicatedWords() {String s = "aaabbbbccdddfgsss";String res = "";int count = 1;for (int i = 1; i < s.length(); i++) {if (s.charAt(i) == s.charAt(i - 1)) {count++;// 如果是最后类字符，需特殊处理if (i == s.length() - 1) {res = res + s.charAt(i) + count;}continue;} else {res = res + s.charAt(i - 1) + count;count = 1;}}System.out.println(res);}}
