PROBLEM:

Is it possible to score R runs within B balls, when you can score at most 6 runs per ball?

EXPLANATION:

At 6 runs per ball, we can score at most 6B runs in B balls.

So,

  • If 6B \lt R there’s no way to reach R at all.
    The answer is No.
  • Otherwise it’s possible to score enough runs (just score 6 on every ball) and the answer is Yes.

TIME COMPLEXITY:

\mathcal{O}(1) per testcase.

CODE:

Editorialist's code (PyPy3) 
r, b = map(int, input().split())
print('Yes' if 6*b >= r else 'No')
