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...
A unique string ID generator for Java. Secure JNanoID uses Java’sSecureRandomto generate cryptographically strong random IDs with a proper distribution of characters. Compact JNanoID generates compact IDs with just 21 characters. By using a larger alphabet than UUID, JNanoID can generate a greater...
