Hi Just thot a Soln Since we need to check whether the length of any path btw any two nodes in a grph it s enough if we checkwhether the Height of DFS tree [/Forest] is max of 2. If so then the ttask underlying is accomplished. Notify if my intution s not crt Open 4 comments Regards Bala On May 5, 8:42 pm, jeth <[EMAIL PROTECTED]> wrote: > Hi, for a long time I'm having a problem with one graph algorithm. > After checking two and spending few days on it I've no more ideas what > to do.
