Question

Implement a Python function with the signature Transfer(S, T) that transfers all elements from the ArrayStack instance S onto the ArrayStack instance T, so that the element that starts at the top of S is the first to be inserted onto T, and the element at the bottom of S ends up at the top of T.

Answer 1

Following are the program in the Python Programming Language.

#define function

def Transfer(S, T):

#set for loop

for i in range(len(S)):

#append in the list

T.append(S.pop())

#return the value of the list

return T

#set list type variable

S = ["a","b","c","d"]

#print the values of the list

print(S)

#set the list empty type variable

T=[]

#call the function

T = Transfer(S, T)

#print the value of T

print(T)

Output:

['a', 'b', 'c', 'd']

['d', 'c', 'b', 'a']

Step-by-step explanation:

Here, we define the function "Transfer()" in which we pass two list type arguments "S" and "T".

• Set the for loop to append the values in the list.
• Then, we append the value of the variable "S" in the variable "T".
• Return the value of the list variable "T" and close the function.
• Then, set the list data type variable "S" and initialize the elements in it and print that variable.
• Finally, we set the empty list type variable "T" and store the return value of the function "Transfer()" in the variable "T" then, print the value of the variable "T".
