求助怎么改输出才能和题目要求一样，难道只能用循环吗

#include <stdio.h>
int qet(int x)
{
int y;
if (x % 2 == 0)
{
y = x / 2;
printf("%d/2=%d\n",x,y);
x = y;
if (x == 1)
{
return 0; //这步怎么改
}
else
{
return qet(x);
}
}
else
{
y = 3 * x + 1;
printf("3*%d+1=%d\n", x, y);
x = y;
return qet(x);
}
}
int main()
{
int x;
scanf_s("%d", &x);
printf("%d", qet(x));
return 0;
}
