Answer:
a)def gcd(a,b):
if(b==0):
return a
else:
return gcd(b,a%b)
a=int(input("Enter first number:"))
b=int(input("Enter second number:"))
GCD=gcd(a,b)
print("GCD is: ")
print(GCD)
b)n=int(input("Enter the number of terms: "))
sum1=0
for i in range(1,n+1):
sum1=sum1+(1/i)
print("The sum of series is",round(sum1,2))
d)# Program to display the Fibonacci sequence up to n-th term
nterms = int(input("How many terms? "))

else:

# update values

ans = isPalindrome(s)
if ans:
