1、该函数并非真正地去除重复元素,只将不重复的元素排在数组最前边,但是去重后的数组最后的元素不变。(注意有一些说法是“去重之后是把重复的元素藏在了最后”, 这种说法是不准确的) 2、针对的是相邻元素,也就是说对于顺序错乱的数组,需要先进行排序,再配合erase后,才可以实现真正意义上的去重(也可以根据返回值...

1 <= words.length <= 100 1 <= words[i].length <= 12 words[i] 仅由英文小写字母组成 样例 思路:Set/Map 将每个单词都按照转换表转换成莫斯电码,然后放入一个集合中去重,那么集合的大小就是不同摩斯电码的数量。 设单词长度最长为 L 。 时间复杂度:O(nL) 需要遍历全部 O(n) 个单词,每个单词都需...
那么unique到底有什么优势呢?比如,假如要得到相邻不同的字符串组,用unique就方便些(好像模拟也不麻烦,就当为了“美”而用unique吧)。sort(words.begin(), words.end());vector::iterator end_unique = unique(words.begin(), words.end());words.erase(end_unique, words.end());...
