I didn't want to upload this , In order to maintain CSDN medal , I hope to understand .
There is no technical content , Is to test some logic , No joy, no spray. .
Enter three numbers （ Floating point data support ）, Determine whether it is a triangle and its type , Side length range [1-200].
The notes are perfect , Self understanding .
