CF1542B Plus and Multiply
Description
There is an infinite set generated as follows:
- $ 1 $ is in this set.
- If $ x $ is in this set, $ x \cdot a $ and $ x+b $ both are in this set.
For example, when $ a=3 $ and $ b=6 $ , the five smallest elements of the set are:
- $ 1 $ ,
- $ 3 $ ( $ 1 $ is in this set, so $ 1\cdot a=3 $ is in this set),
- $ 7 $ ( $ 1 $ is in this set, so $ 1+b=7 $ is in this set),
- $ 9 $ ( $ 3 $ is in this set, so $ 3\cdot a=9 $ is in this set),
- $ 13 $ ( $ 7 $ is in this set, so $ 7+b=13 $ is in this set).
Given positive integers $ a $ , $ b $ , $ n $ , determine if $ n $ is in this set.
Input Format
The input consists of multiple test cases. The first line contains an integer $ t $ ( $ 1\leq t\leq 10^5 $ ) — the number of test cases. The description of the test cases follows.
The only line describing each test case contains three integers $ n $ , $ a $ , $ b $ ( $ 1\leq n,a,b\leq 10^9 $ ) separated by a single space.
Output Format
For each test case, print "Yes" if $ n $ is in this set, and "No" otherwise. You can print each letter in any case.
Explanation/Hint
In the first test case, $ 24 $ is generated as follows:
- $ 1 $ is in this set, so $ 3 $ and $ 6 $ are in this set;
- $ 3 $ is in this set, so $ 9 $ and $ 8 $ are in this set;
- $ 8 $ is in this set, so $ 24 $ and $ 13 $ are in this set.
Thus we can see $ 24 $ is in this set.
The five smallest elements of the set in the second test case is described in statements. We can see that $ 10 $ isn't among them.
