Question

Write a program to print the sum of prime numbers from 50 to 750.​

Answer 1

Required Answer:-

Question:

• Write a program to find out the sum of prime numbers from 50 to 750.

Solution:

Here comes the program.

1. In Java.

public class Sum {

 public static void main(String[] args) {

   int i, sum=0;

   for(i=50;i<=750;i++) {

     if(isPrime(i))

       sum+=i;

   }

   System.out.println("Sum: "+sum);

 }

 static boolean isPrime(int n) {

    for(int i=2;i<=n-1;i++) {

       if(n%i==0)

         return false;

    }

    return true;

 }

}

2. In Python.

def isPrime(n):

for i in range(2,n):

 if n%i==0:

  return False

return True

sum=0

for i in range(50,750+1):

if isPrime(i):

 sum+=i

print("Sum: ",sum)

Algorithm:

1. START
2. Iterate a loop within range 50 - 750.
3. Check if any number is prime or not. If prime, add them up and store the sum in sum variable.
4. Display the sum.
5. STOP
