Answer: Both technicians are correct.

It is true when technician A says that the octane rating of a gasoline is used to measure the antiknock properties of a gasoline. Octane rating measure the resistance of gasoline to engine knocking in spark-ignition internal combustion of engines.

On other hand, technician B is also correct because a normal combustion occurs smoothly, controlled burning of air and fuel mixture then progresses across the combustion chamber from the point of ignition.

Given an n-element array X, algorithm D calls algorithm E on each element X[i]. Algorithm E runs in O(i) time when it is called
krek1111 [17]

Answer:

O(n^2)

Explanation:

The number of elements in the array X is proportional to the algorithm E runs time:

For one element (i=1) -> O(1)

For two elements (i=2) -> O(2)

.

.

.

For n elements (i=n) -> O(n)

If the array has n elements the algorithm D will call the algorithm E n times, so we have a maximum time of n times n, therefore the worst-case running time of D is O(n^2)

A contact list is a place where you can store a specific contact with other associated information such as a phone number, email
Arte-miy333 [17]

Answer:

# The user in prompted for input and stored in userInput

userInput = str(input("Enter the contact: "))

# The user input is splitted and stored in splitUserInput

# splitUserInput is a list because split returns a list

splitUserInput = userInput.split(" ")

# The user is prompt to enter the search contact

# The search contact will have the first letter capitalize

# should it be entered in lower case all through

searchContact = str(input("Enter the search contact: "))

# loop through the list

for i in range(len(splitUserInput)):

   # compare if the string at any value of i

   # is the same as the searchContact

   # we display the string ahead of it

   # by adding 1 to the index

   if(splitUserInput[i] == searchContact):

       print(splitUserInput[i + 1])

Explanation:

A sample screenshot is attached. The code is written in Python 3 and well commented.

The program prompt the user for input then split the input into a list. It then asked for a contact to search for. It begins looping through the list, if the search contact is found at any index, then it prints what is in front of the index.
