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...

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());...
Unique Number of Occurrences in Python - Suppose we have an array, and we need to check whether each element has a unique number of occurrences. If no such element exists, we return false; otherwise, we return true. For example, given the array [1, 1, 2,
