Write a code block to encode strings from original messages, using our custom encoding. To do so: Initialize a variable called c
blondinia [14]

Answer:

  1. custom_encoded = ""
  2. custom_message = "this is a pen"
  3. custom_encoding = {
  4.    "a": "1",
  5.    "e": "2",
  6.    "i": "3",
  7.    "o": "4",
  8.    "u": "5"
  9. }
  10. for c in custom_message:
  11.    if(c in custom_encoding):
  12.        custom_encoded = custom_encoded + custom_encoding[c]
  13.    else:
  14.        custom_encoded = custom_encoded + c
  15. print(custom_encoded)

Explanation:

The solution code is written in Python 3.

Let's define a variable custom_encoded with an empty string (Line 1).

Create another variable custom_message and set a sample string to it (Line 2).

Create one more variable custom_encoding to hold the mapping values between vowel and their respective encoded character (Line 3-9).

Create a for loop to loop through all the character in custom_message (Line 11) and in the loop check if the current character is found in custom_encoding dictionary, if so, use the current character to loop up the dictionary for the encoded value and add the encoded string to custom_encoded (Line 12-13). Otherwise, just add the current character to custom_encoded (Line 14-15).

At the end, print the custom_encoded to terminal and you shall get th3s 3s 1 p2n

Imagine that you are designing an application where you need to perform the operations Insert, DeleteMaximum, and Delete Minimum
fiasKO [112]

Answer:

A stack data structure should be used. The time complexity of the insert, delete minimum and maximum operation is O(1).

Explanation:

The stack data structure is an indexed structure that holds data in an easily retrievable way. Data is held in a first-in last-out method as elements in the structure are popped out from the end of the stack when retrieved sequentially.

The worst-case time complexity of getting the minimum and maximum elements in a stack and deleting it is O(1), this is also true for inserting elements in the stack data structure.
