diff: +# Let's take the input series from the User
  +# First 2 elements indicates series...
  +# 3rd element indicates the nth term to find in the fibonacci series.
  x=input("").split(' ')
  +
  +# Put the first element in series in x[0] & second element in x[1]
  first=int(x[0])
  second=int(x[1])
  +
  +# Convert the data-type into Integer for more convienence
  r=int(x[2])
  r-=2
  +
  +# The first two series indicates the Fibonacci series.
  +# The first two terms of the sequence are first and second, which gives us a modified Fibonacci sequence of { 0,1,1,2,3,5...}
  +# if n=3. it will return 3rd element.
  for g in range(r):
  z=first
  zz=second
  - second=zz*zz+z
  - first=zz
  + second=zz*zz+z # Updating until the nth term
  + first=zz # next series of Fibonacci series.
  +
  +# Let's print the nth value which was stores in second element
  print(second)
