Problem Statement
Answer the following $T$ queries.
In the $i$-th query ($1\leq i\leq T$), you are given a positive integer $N_i$. Find the number of tuples $(a, b, c, d)$ of positive integers not exceeding $N_i$ that satisfy $a^b=c^d$.
Input
$T$ $N_1$ $N_2$ $:$ $N_T$
- $1\leq T \leq 50$
- $1\leq N_i\leq 10^9$
- All inputs are integers.
Output
Output $T$ lines. On the $i$-th line ($1\leq i\leq T$), output the answer to the $i$-th query. It can be shown that, under the constraints of this problem, the answer fits in a $64$-bit signed integer type.
Sample
Sample 1
Input
4 1 2 5 314
Output
1 6 49 206958
For example, since $2^4=4^2$, $(a, b, c, d)=(2, 4, 4, 2)$ satisfies the condition in the $3$rd and $4$th queries.
