+Reverse engineering, or reverse engineering (in English: Reverse engineering),
+is the study of something by breaking it down into its components and learning how it works.
+Today, reverse engineering is widely used in the world of computers, when studying computer code.

+Here is a piece of code that asks the user to enter a password as input. The code checks whether 
+the entered password is correct (that is, meets certain conditions) or not and prints an
+appropriate output to the screen.
+'''

+import functools
+def function(num, item):
+    return num + 1
+password = input("Enter Your password (integers only): ")
+lst = list(map(int, password))
+magic = functools.reduce(function, lst)
+result = (lambda x: x % 4 == 0)(magic)
+if result:
+    print("Correct password!")
+else:
+    print("Wrong password.")
+    
+#  After you understand how the code works, choose from the following inputs the input for which 
+# the output will be printed: "!Correct password"
