Solution a)

num1=int(input("Enter first number "))
num2=int(input("Enter second number "))
product=0
for i in range (1,num2+1): 
     product=product+num1      
print("The multiply is: ",product)


Solution b)

def recur_fibo(n):
    if n<=1:
        return n
    else:
        return(recur_fibo(n-1) + recur_fibo(n-2))
nterms=int(input("Enter the number of terms"))
print("Fibonacci series:")
for i in range(nterms):
    print(recur_fibo(i), end=" ")
