Question

P1. Se da un vector de n numere intregi. Sa se formeze un alt vector care sa contina doar numerele palindromice cu exact k cifre impare.
Ex: k=2, n=7, v: 23832, 88988, 33, 1234, 8888, 778, 585
Se afiseaza alt vector : 23832, 33, 585
Dau 50 pct

Answer 1

#include <iostream>

bool cifre_impare_palindrom(const int n, const size_t k) {

size_t c = 0;

int m = n, x = 0;

while (m) {

    x *= 10;

    x += m % 10;

 c += m & 1;

 m /= 10;

}

return c == k && x == n;

}

int main() {

size_t i, k, n, c = 0;

std::cin >> k >> n;

int temp, *t = new int[n];

for (i = 0; i < n; ++i) {

 std::cin >> temp;

 if (cifre_impare_palindrom(temp, k))

  t[c++] = temp;

}

for (i = 0; i < c; ++i)

 std::cout << t[i] << ' ';

 

delete[] t;

}
