Java实现 洛谷 P1035 级数求和

import java.util.Scanner;


public class Main {

	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		
		double k = in.nextDouble();
		
		double i = 1;
		double sn = 0;
		while(! (sn > k) ){
			sn = sn + 1/i;
			i++;
		}
		
		System.out.println( (int)(i-1) );
	}
