• Problem Description

  
  Write a program to find the intersection of two lists

• CODING ARENA

• def intersection(a, b):

      return list(set(a) & set(b))

  def main():

      alist=[]

      blist=[]

      n1=int(input())

      n2=int(input())

      for x in range(0,n1):

          element=int(input())

          alist.append(element)

      for x in range(0,n2):

          element=int(input())

          blist.append(element)

      ans=[]

      for x in alist:

          for y in blist:

              if(x==y):

                  ans.append(x)

      print("The intersection is")

      print(ans)
