Chapter 6-2. Use function to find the sum of prime numbers (20 points)

Use a function to find the sum of prime numbers

prime (p), where the function prime returns True when the user passes in the parameter p as a prime number, otherwise returns False. PrimeSum (m, n), the PrimeSum function returns the sum of all prime numbers in the interval [m, n]. The title guarantees that the parameter 1 <= m <n passed by the user.

Function interface definition:

在这里描述函数接口：
prime(p)，返回True表示p是素数，返回False表示p不是素数
PrimeSum(m,n)，函数返回素数和

 

Sample referee test procedure:

/* 请在这里填写答案 */

m,n=input().split()
m=int(m)
n=int(n)
print(PrimeSum(m,n))

 

Sample input:

Here is a set of inputs. E.g:

1 10

 

Sample output:

The corresponding output is given here. E.g:

17
