Squares and Cubes
Description
Polycarp likes squares and cubes of positive integers. Here is the beginning of the sequence of numbers he likes: $1$, $4$, $8$, $9$, ....
For a given number $n$, count the number of integers from $1$ to $n$ that Polycarp likes. In other words, find the number of such $x$ that $x$ is a square of a positive integer number or a cube of a positive integer number (or both a square and a cube simultaneously).
The first line contains an integer $t$ ($1 \le t \le 20$) — the number of test cases.
Then $t$ lines contain the test cases, one per line. Each of the lines contains one integer $n$ ($1 \le n \le 10^9$).
For each test case, print the answer you are looking for — the number of integers from $1$ to $n$ that Polycarp likes.
Input
The first line contains an integer $t$ ($1 \le t \le 20$) — the number of test cases.
Then $t$ lines contain the test cases, one per line. Each of the lines contains one integer $n$ ($1 \le n \le 10^9$).
Output
For each test case, print the answer you are looking for — the number of integers from $1$ to $n$ that Polycarp likes.
