Reverse bits of a given 32 bits unsigned integer. For example, given input 43261596 (represented in binary as 00000010100101000001111010011100), return 964176192 (represented in binary as 00111001011110000010100101000000). Follow up: If this function is called many times, how would you optimize it?
addAll(collection a);将集合a全部添加到集合中 2,删除 remove(e); removeAll(collection a); 从集合中去除集合a中的对象 clear(); 清空集合 3,判断。 contains(e); 集合是否有e元素,有则返回ture isEmpty(); 判断是否为空 4,获取 iterator(); 获取迭代器 ...
