Question

Answer 1

def isprime(n):
    if n<=1:
        return False
    for i in range(2,n):
        if n%i==0:
            return False
    return True
def f(n):
    count = 0
    s = 0
    while count<10 and n>1:
        if isprime(n):
            count += 1
            s += n
        n -= 1
    return s


p = int(input())
print(f(p))
