Examples:
[1 2 1000] ---> false
[3 4 5] ---> true
[5 5 5] ---> true

I wanted to try out the Hankel here. This is more than necessary. It checks to see that the sum of all pairs of sides are greater than the remaining side. You really only need to do this to compare against the maximum length side.

This is just bad, only gaming the test suit. There is nothing to be learned from this.
