感觉我脑洞太飘逸了...O(∩_∩)O哈哈~

坚决不重复造轮子、

 

AC代码：

1 import java.util.Scanner; 2  3 public class Main { 4  5     public static void main(String[] args) { 6          7         Scanner sc=new Scanner(System.in); 8         int times=sc.nextInt(); 9         while(times-->0){10             System.out.println(solve(sc.nextInt()));11         }12         13     }14     15     public static int solve(int n){16         return Integer.toBinaryString(n).replaceAll("0","").length();17     }18     19 }
