int a[101] = {0},b[1000];
scanf("%d",&n);
for(i = 0;i < n;i++)
{

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

{
if(temp > 1)
{
if(temp % 2 == 0)
{
temp = temp / 2;
b[j] = temp;
}
else
{
temp = temp * 3 + 1;
b[j] = temp;

}
for(k = 0;k < n;k++)
{

}
}
}
else

}
for(i = 0;i < n - 1;i++)
{
for(j = 0;j < n - i - 1;j++)
{
if(a[j] < a[j + 1])
{
temp1 = a[j + 1];
a[j + 1] = a[j];
a[j] = temp1;
}
