Pretty Good Cube Root
Given a positive integer $x$, the cube root of $x$ may or may not be an integer. We’ll define an approximate cube root of $x$ as the positive integer $y$ such that $y^3$ is as close is possible to $x$.
Input has up to $100$ lines with one positive integer per line. Each integer may have as many as $500$ digits. Input ends at the end of file.
For each input integer, print out its approximate cube root.
