Compare lists function:

Syntax: compare(list,list)
    WARNING: AN EMPTY LIST NAMED "c" MUST BE CREATED BEFORE CALLING THIS FUNCTION WITH THE: "c = []" COMMAND
  
This compares two lists and finds the first common element in both the lists..
It returns 1 if a match is found or 0 if a match is not found in the 2 input lists..
If a match is found, it stores the match in a list "c".. If called repeatedly on different lists, it will store all the matches in list "c"..'''

Eg:
import shortestpath as sp
a = [1,2,3,4]
b= [5,6,7,2]
sp.compare(a,b)


This example will return 1.. also it will create a list c in which the number 2 will be present.
