Timelimit: 1

Write an algorithm to calculate and write the value of S, S being given by:
S = 1 + 1/2 + 1/3 + … + 1/100

Input

There is no input in this problem.

Output

The output contains a value corresponding to the value of S.
The value should be printed with two digits after the decimal point.

Solution in Java:

package URI_Problems_solution;

public class URI_1155 {

    public static void main(String[] args) {

         //S = 1 + 1/2 + 1/3 + … + 1/100

         float S = 0;

         for (float i = 1; i <= 100; i++) {

             S += (1 / i);

         }

         System.out.printf("%.2f\n",S);

    }

}

Solution in C:

1. #include <stdio.h>
2. int main()
3. {
4. double d = 0, i;
5. for (i = 1; i <= 100; ++i)
6. d += 1/i;
8. printf("%.2lf\n", d);
9. return 0;
10. }

Solution in C++:

1. #include <cstdio>
2. using namespace std;
3. 
   
4. int main()
