Problem Statement
We have a sequence of length $1$: $A=(X)$. Let us perform the following operation on this sequence $10^{100}$ times.
Operation: Let $Y$ be the element at the end of $A$. Choose an integer between $1$ and $\sqrt{Y}$ (inclusive), and append it to the end of $A$.
How many sequences are there that can result from $10^{100}$ operations?
You will be given $T$ test cases to solve.
It can be proved that the answer is less than $2^{63}$ under the Constraints.
Constraints
- $1 \leq T \leq 20$
- $1 \leq X \leq 9\times 10^{18}$
- All values in input are integers.
Input
Input is given from Standard Input in the following format:
Each case is in the following format:
``` $X$ ```Output
Print $T$ lines. The $i$-th line should contain the answer for $\rm case_i$.

In the first case, the following five sequences can result from the operations.
- $(16,4,2,1,1,1,\ldots)$
- $(16,4,1,1,1,1,\ldots)$
- $(16,3,1,1,1,1,\ldots)$
- $(16,2,1,1,1,1,\ldots)$
- $(16,1,1,1,1,1,\ldots)$
