Question: Special Numbers
Solution: In C
int specialNumbers(int L, int R)
{
int ans = 0;
if ( L < 369 && R >= 369)
L = 369;
while (L <= R)
{
int count3 = 0 , count6 = 0, count9 = 0;
for(int i=L; i>0; i/=10)
{
if ( i%10 == 3)
count3 ++;
else if (i%10 == 6)
count6 ++;
else if (i % 10 == 9)
count9 ++;
}
if (count3 > 0 && count3 == count6 && count3 == count9)
ans ++;
L++;
}
return ans;
}
