Answer 1

#include <iostream>

size_t suma(size_t n) {

size_t s = 0;

for (size_t i = 2; i <= (n >> 1); ++i)

if (!(n % i))

s += i;

return s;

}

void subperfect(size_t a, size_t b) {

bool test = false;

while (a <= b) {

if (b < suma(b)) {

std::cout << b << ' ';

test = true;

}

--b;

}

if (!test)

std::cout << "nu exista";

}

int main() {

size_t a, b;

std::cin >> a >> b;

subperfect(a, b);

}
