PRoblem Description There are many lamps in a line. All of them are off at first. A series of Operations are carried out on these lamps. On the i-th operation, the lamps whose numbers are the multiple of i change the condition ( on to off and off to on ).
Input Each test case contains only a number n ( 0< n<= 10^5) in a line.
Output Output the condition of the n-th lamp after infinity operations ( 0 - off, 1 - on ).
Sample Input 1 5
Sample Output 1 0
import java.util.*;class Main{ public static void main(String args[]){ Scanner sc=new Scanner(System.in); while(sc.hasNext()){ int n=sc.nextInt(); int m=(int)Math.sqrt(n); if(n==m*m){ System.out.println("1"); }else{ System.out.println("0"); } } }}新闻热点
