代码实现

import math
start,end = map(int,input().split());count = sum = 0
if start == 1: start = 2
for i in range(start,end+1):
    temp = int(math.sqrt(i));flag = 0
    for j in range(2,temp+1):
        if (i%j == 0):
            flag = 1;
            break
    if(flag == 0):
        count+=1
        sum+=i
print("%d %d" %(count,sum))
