## Description
# --description--
Find solutions to the *sum to one hundred* puzzle.
Add (insert) the mathematical operators **+** or **─** (plus or minus) before any of the digits in the decimal numeric string **123456789** such that the resulting mathematical expression adds up to a particular sum (in this iconic case, **100**).

Find solutions to the <i>sum to one hundred</i> puzzle.
Add (insert) the mathematical operators <b>+</b> or <b>─</b> (plus or minus) before any of the digits in the decimal numeric string <b>123456789</b> such that the resulting mathematical expression adds up to a particular sum (in this iconic case, <b>100</b>).
Example:
<pre><b>123 + 4 - 5 + 67 - 89 = 100</b></pre>
</section>
## Instructions
# --instructions--
<section id='instructions'>
Write a function that takes a number as parameter. The function should return an array containing all solutions for the given number. The solutions should be strings representing the expressions. For example: "1+23-456+78-9". Sort the array before returning it.
</section>
## Tests

<section id='tests'>
`sumTo100` should be a function.
