Question

Express the algorithm to compute the sum of cubes of all numbers from 1 to N in a flowchart(i.e. 13+23+33+……+N3)

Answer 1

13+23+33.......+N3

Input n=1

Answer 2

Example:-

• Input n=1
• Output=82
• 13+23+33+13=82

Programme:-

• Simple Java program to find sum of series
• // with cubes of first n natural numbers
• import java.util.*;

• import java.lang.*;

• class GFG {

• /* Returns the sum of series */

• public static int sumOfSeries(int n)

{

• int sum = 0;
• for (int x = 1; x <= n; x++)
• sum += x * x * x;

• return sum;

}

• // Driver Function

• public static void main(String[] args)

{

• int n = 1;
• System.out.println(sumOfSeries(n));

}

}
