Algoritm (pseudocod)
intregi x, nr=0, x1, p=1
citeste x
x1 primeste x
cat timp x1!=0 executa
{
p primeste p*x1/10;
x1 primeste x1/10;
}
daca p%2=0 atunci nr primeste nr+1
cat timp x%3!=0 executa
{
citeste x
x1 primeste x
cat timp x1!=0 executa
{
p primeste p*x1/10;
x1 primeste x1/10;
}
daca p%2=0 atunci nr primeste nr+1
}
scrie nr
C++
#include <iostream>
