> 其实,a-1和b+1是一样的,关键是加边(a,b,c)要满足b-a》=c!
> 1201 题目条件是bi-ai+1>=ci即是(bi+1)-ai>=ci 加入(ai,bi+1,ci)
>                         或者bi-(ai-1)>=ci  加入(ai-1,bi,ci)
> 1716 a-b之间要有2个数(即c=2)且a<b  即是 b-a>=1   即 (b+1)-a>=2    (c==2)
>                                 加入(a,b+1,c)
>                                 或者(a-1,b,c)也一样!
