• [tab]
• C++

• #include<iostream>
  using namespace std;
   
  int main()
  {
  	int d=0;
  	long long a,b;
  	cin>>a>>b;
  	while(a<=b)
  	{
  		a=a*3;
  		b=b*2;
  		d++;
  	}
  	cout<<d;
  	return 0;
  }

• Python 3

• num_array = input().split()
   
  num1 = int(num_array[0])
  num2 = int(num_array[1])
  count = 0
   
  while num1 <= num2:
      num1 *= 3
      num2 *= 2
      count += 1
      
  print(count)
