Valid equivalent partitions in a range from -100 to 100?
<p>I can't figure out this question. </p>

<p>A program which accepts an integer in the range -100 to +100: </p>

<p><strong>1)</strong> How many valid equivalent partitions are there? </p>

<p><strong>2)</strong> For which range what are minimum and maximum values? </p>

<p><strong>3)</strong> Using <code>BVA</code>, what values need to be checked for the partitions?</p>

<p>So..., according to the equivalence testing, you can have a valid and invalid value. I supposed the invalid values would be anything less than -100 and greater than 100. However I can't find information about how to get equivalent partitions.</p>

<p>I mean, I can chose and say that it has 20 equivalent partitions, for example: -100 to -90 | -89 to 70 etc..., but: <strong>Is there a way to get this?</strong> </p>

<p>For the other questions: <strong>Is it possible get the previous partition so the minimum value would be -100 and the maximum -90?</strong></p>
