# DIFFICULTY:

TBD

# PREREQUISITES:

None

# 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.
