C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int m,n,sum=0;
	cin>>m>>n;
	for(int i=m;i<=n;i++){
		if(i%17==0)sum+=i;
	}
	cout<<sum<<endl;
	return 0;	
}

Python :

# coding=utf-8
m = int(input())
n = int(input())
s = 0
for i in range(m, n + 1):
    if (i % 17 == 0):
        s += i
print(s)
