记$V=2^{20}-1$,即值域范围,也可以作为"全集" 显然与$a_{i}$的顺序无关,对所有$a_{i}$维护一棵trie树 关于如何维护这棵trie树,考虑使用分裂+合并的方式,即:1.分裂出区间对应的trie树:2.操作分裂出的trie树:3.合并分裂出的tire树和原trie树 (关于时间复杂度后面会进行统一分析,暂时不需要考虑) 对于分裂(第1步),使用类似线段树查询的方法 对于合并(第3步),使用类似线段树合并的方法(即在其中一个子树为空时直接选择另一个子树) 对于操作…

Write a function that takes an unsigned integer and returns the number of ’1' bits it has (also known as the Hamming weight). For example, the 32-bit integer ’11' has binary representation 00000000000000000000000000001011, so the function should retu…
