 this function defines the weight between two vertices
 we are looking at a directed graph, 
  where a->b and b->a will have different weights
def min_click_path( ch_src, ch_dst  ){
   abs_delta = #|ch_src - ch_dst | // this is done by using +/- channel button 
   dst_digits = size( ch_dst , 10 ) // this is the abs number press 
   #(m,M) = minmax( abs_delta, dst_digits )
   m // minimal path from src to dst 
now just assume
from src to ch_dst 
respond with the weight for ch_dst
