One of the numbers 1 to 9 is selected and the following operation is performed.

Multiply a given number by 3 first, and if the result is 10 or more, leave only the number of digits in the work and multiply it by 3 again.

Write a program that outputs the number of times multiplied by 3 until the operation is first selecte

TT... plz

#include <stdio.h>

int main(void)

{

int a = 1;

int count, b;

scanf("%d", &a);

if (a>0, a<10)

{

while(b=a)

{

b = a * 3;

if(b > 10)

{

b = b % 10;

count++;

printf("%d",count);
