Using a wireless technology known as Near-field communication (NFC), once activated on the smartphone, allows payments or purchases to be made at select stores.

<h3>What is Near-field communication (NFC)?</h3>

NFC is a set of short-range wireless technologies that typically require a distance of 4 cm or less to initiate a connection.

<h3>Characteristics of Near-field communication (NFC)</h3>

  • For it to work, it is necessary to place two spiral-type antennas within these close electromagnetic fields.

  • This technology is built on radio frequency identification, which allows a gadget to send radio waves to another gadget or another tag and trigger a certain action.

  • The NFC acts on the smartphones just like the RFID chips of the bank cards with which you can make payments or purchases.

Therefore, we can conclude that the NFC allows two devices to exchange data when in close proximity to each other.

Implement a Python function with the signature Transfer(S, T) that transfers all elements from the ArrayStack instance S onto th
Mashutka [201]

Answer:

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)

<u>Output:</u>

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

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

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".
