Solution

题目大意:根据要求翻译句子

思路:转换成单词数组,遍历数组,根据要求转换单词

Java实现:

用Java8的流实现,效率太低

public String toGoatLatin(String S) {    final String[] arr = S.split(" ");    final int[] idx = {0};    return Arrays.stream(S.split(" "))        .map(s -> convert(s, ++idx[0]))        .reduce("", (s1, s2) -> s1 + " " + s2).trim();}String convert(String ori, int count) {    String pre = "";    // begin with vowel aeiou    char first = ori.charAt(0);    if (first == 'A' || first == 'a'        || first == 'E' || first == 'e'        || first == 'I' || first == 'i'        || first == 'O' || first == 'o'        || first == 'U' || first == 'u'       ) {        pre = ori;    } else {        // begin with consonant not aeiou        pre = ori.substring(1) + first;    }    // add a    char[] a = new char[count];    for (int i = 0; i < count; i++) {        a[i] = 'a';    }    return pre + "ma" + String.valueOf(a);}

public String toGoatLatin(String S) {    StringBuilder sb = new StringBuilder();    int count = 1;    for(String tmp : S.split(" ")) {        sb.append(convert(tmp, count++)).append(" ");    }    return sb.toString().trim();}
