測試用例太惡心了，受不鳥啊

class Solution {public static final char NO_NEW_LINE = '\'';public List<String> removeComments(String[] source) {boolean pending = false;List<String> result = new ArrayList<>();for (int i = 0; i < source.length; i++) {if (!pending) { // 左注釋符已閉合int i1 = source[i].indexOf("//");if (i1 < 0) i1 = source[i].length();int i2 = source[i].indexOf("/*");if (i2 < 0) i2 = source[i].length();if (i1 == i2) { // 本行無注釋add(result, source[i]);} else if (i1 < i2) { // 本行先出現//String s = source[i].substring(0, i1);add(result, s);} else { // 本行先出現/*String s = source[i].substring(0, i2);if (s.length() > 0) add(result, s + NO_NEW_LINE);source[i] = source[i].substring(i2 + 2);pending = true;i--;}} else { // 左注釋符未閉合int i2 = source[i].indexOf("*/");if (i2 >= 0) {source[i] = source[i].substring(i2 + 2);pending = false;i--;}}}return result;}public void add(List<String> result, String s) {if (!result.isEmpty()) {String tail = result.get(result.size() - 1);int len = tail.length();if (tail.charAt(len - 1) == NO_NEW_LINE) { // implicit newline characters can be deleted by block commentsresult.set(result.size() - 1, tail.substring(0, len - 1) + s);return;}}if (s.length() > 0) result.add(s);} }
