/*
Apollo likes perfect squares of integers (e.g. 1, 4, 9, 25 etc). You are given a hexadecimal string, s (e.g. "1a", "12b9c7"). Find out the minimum number of pieces, i, to split this string such that each of the i pieces is a hexadecimal representation of a perfect square. Note that this may not be possible for every hexadecimal string.

Complete the getMin function in your editor, in a language of your choice. It has one parameter: a string, s, a valid representation of a hexadecimal number. It must return an integer denoting the value of i; if there is no such positive integer i, return ?1.

Bonus: Performance is a concern. An unoptimized solution will see timeouts in some of the large test cases.

Input Format
The locked stub code in your editor reads a hexadecimal string, s, from stdin and passes it to your function. The input will conform to the following formats:

First, install nginx for mac with "brew install nginx".

Then follow homebrew's instructions to know where the config file is.

1. To use https you will need a self-signed certificate: https://devcenter.heroku.com/articles/ssl-certificate-self
2. Copy it somewhere (use full path in the example below for server.* files)
3. sudo nginx -s reload
4. Access https://localhost/

Edit /usr/local/etc/nginx/nginx.conf:
