Needed in python thank youSolutionimport timeit def builtInp

Solution

import timeit
def builtInput():
   list = [4,1,9,3,5]
   num = 13
   tuple = (list,num)
   return tuple
  

def pairs1(list,num):
   for i in range(len(list)):
       for j in range(1,len(list)):
           if(list[i]+list[j]==num):
               return True
   return False

def pairs2(list,num):
   list.sort()
   for i in range(len(list)):
       temp = num - i
       # search for the other number in list or not.
       if(temp in list[i:]):
           return True
   return False
def timeAnalysis():
   \" Time between start and end is the running time of the funciton.\"
   start = timeit.default_timer()
   print pairs1([4,1,9,3,5],13)
   stop = timeit.default_timer()
   print stop - start
   start = timeit.default_timer()
   print pairs2([4,1,9,3,5],13)
   stop = timeit.default_timer()
   print stop - start

timeAnalysis()

# sample output

#

# pairs2 would be taking lesser time compared to pairs1.
