P9063 [yLOI2023] Decomposing “Zhi Factors”
Description
Given a positive integer $n$, factorize $n$ into prime factors.
Let $n = p_1 \times p_2 \times p_3 \times \dots \times p_x$, where each $p_i$ is a prime number.
If all $p_i$ are odd, then $n$ is called a “Zhi Factor Number” (“只因数”).
Now, given several values of $n$, determine whether $n$ is a “Zhi Factor Number”.
Input Format
**This problem contains multiple groups of testdata within a single test case.**
The first line contains an integer $T$, the number of testdata groups.
The next $T$ lines each contain an integer $n$, representing one group of data.
Output Format
For each group of data, output one string per line. If $n$ is a “Zhi Factor Number”, output `Yes`; otherwise output `No`.
Explanation/Hint
### Constraints
There are $10$ test points in total. For the $i$-th test point, $T = \max(1, i - 1)$.
- For $30\%$ of the data, $n \leq 3$.
- For $50\%$ of the data, $n \leq 10$.
- For another $10\%$ of the data, $n$ is odd.
- For another $10\%$ of the data, $n$ is even.
- For $90\%$ of the data, $n \leq 10^9$.
- For $100\%$ of the data, $1 \leq T \leq 9$, $2 \leq n \leq 10^{18}$.
