l1=[]
l2=[]
print('Enter the first list elements: ')
for i in range(N1):
  l1.append(int(input('')))
print('Enter the second list elements: ')
for i in range(N2):
  l2.append(int(input('')))
s1=int(input('First List Element to be searched: '))
s2=int(input('Second List Element to be searched: '))
ind=int(input('Index number of the list to be added: '))
ele=int(input('Element to be added in the list:'))

l3=l1+l2
print('The Extended List')
print(l3)
print('Index for {} = {}'.format(s1,l3.index(s1)))
print('Index for {} = {}'.format(s2,l3.index(s2)))
print('After Inserting')
l3.insert(ind,ele)
print(l3)
