The computer scientists Richard Conway and David Gries once wrote: The absence of error messages during translation of a computer program is only a necessary and not a sufficient condition for reasonable [program] correctness. Rewrite this statement without using the words necessary or sufficient.

Answers

Answer 1

Answer:

A computer program is not reasonably correct if it has no error messages during translation.

 

Explanation:

First, we need to understand what the statement means, and we also need to identify the keywords.

The statement means that, when a program does not show up error during translation; this does not mean that the program is correct

Having said that:

We can replace some keywords as follows:

absence of error messages := no error messages

The process of saving information to a secondary storage device is called...

Answers

Answer:

The process of saving information to a secondary storage device is referred to as embedding.

Explanation:

The process of saving information to a secondary storage device is called embedding.

What is embedding?

One technique a writer or speaker could use to lengthen a sentence is embedding. When two clauses fall into the same category, they can frequently be nested inside of one another. For illustration: The baked product was presented by Norman. My sister didn't know about it.

Her thumb had the thorn embedded in the surface there, locked onto something. A person or thing is said to be embedded when it is a highly important or powerful part of that person, item, etc. Guilt was deeply engrained in my conscience.

The embedding strategy modifies each video frame slightly in an attempt to try covert or undetectable data concealing.

Thus, it is embedding.

Assume in the for loop header, the range function has the three arguments: range (1, 10, 3), if you were to print out the value of the variable
in the for loop header, what will be printed out? List the values and separate them with a comma.

Answers

Answer:

1, 4, 7

Explanation:

The instruction in the question can be represented as:

for i in range(1,10,3):

   print i

What the above code does is that:

It starts printing the value of i from 1

Increment by 3

Then stop printing at 9 (i.e.. 10 - 1)

So: The sequence is as follows

Print 1

Add 3, to give 4

Print 4

Add 3, to give 7

Print 7

Add 3, to give 10 (10 > 10 - 1).

So, it stops execution.

Def locate_substring(dna_snippet, dna): This function takes in two strings, dna_snippet and dna, where dna_snippet is a substring of dna, and returns all locations of the substring as a list of integers. In other words, dna_snippet may exist in multiple locations within dna; you should return the beginning index position of each occurrence of dna_snippet inside of dna. Example: * Sample DNA snippet (substring): "ATAT" * Sample DNA string: "GATATATGCATATACTT" * The returned position list: [1, 3, 9]

Answers

Answer:

In Python. The function is as follows:

def locate_substring(dna_snippet, dna):

   res = [i for i in range(len(dna_snippet)) if dna_snippet.startswith(dna, i)]  

   print("The returned position list : " + str(res))

Explanation:

This iterates defines the function

def locate_substring(dna_snippet, dna):

Check for all occurrence

   res = [i for i in range(len(dna_snippet)) if dna_snippet.startswith(dna, i)]  

print all occrrence

   print("The returned all position list : " + str(res))

Following is the Python program to the given question.

Python

According to the question,

DNA Series: GATATATGCATATACTTDNA

Snippet: ATAT

Program: def locate_substring (dna_snippet, dna):

start = 0 while True: start = dna.

find(dna_snippet, start) #finding the first occurrence of dna_snippet in dna.

if start == -1: return # if dna.find() returns -1 yield start #Resumes next execution start += 1dna=input ("Enter the DNA sequence: ") dna_snippet=input

("Enter the DNA snippet: ") print(list(locate_substring(dna_snippet,dna )))

Program Explanation: Defining a function.

An infinite loop is being utilized just to produce the indexes from which dna snippet begins.

Determining the initial occurrence of dna snippet inside dna. storing the new occurrences of dna snippet throughout the starting point.

Whenever dna.find() returns minus one, it means there was no occurrence identified and the method should be exited.

Explanation:

how to learn python ?

Answers

Answer:

See below.

Explanation:

To learn python programming language, first, you have to know the basic. Surely, you may recognize this function namely print()

print(“Hello, World!”) — output as Hello, World!

First, start with familiarizing yourself with basic function such as print. Then step up with arithmetic and declare or assign variable then list.

Here are example of functions:

1.) print(argument) — If argument is a string (word-typed), make sure to use “” or ‘’ or else it’ll output an error and say the argument is not defined.

print(“Hi, Brainly”) will output Hi, Brainly

print(2+3) will output 5

Numerical data or numbers do not necessarily require “ “ or ‘ ‘

print(3+3) will output 6 but print(“3+3”) will output 3+3 which is now a string.

2.) type(argument) - this tells you which data/argument it is. There are

< class ‘str’ > which is string, meaning it contains “ “ or ‘ ‘< class ‘int’ > which is integer< class ‘float’ > which is decimal (20.0 is also considered as float, basically anything that contains decimal is all float type)< class ‘list’ > which is a list. List is something that contains elements within square brackets [ ]

etc.

Make sure you also do print(type(argument)) as well so it will print out the output.

3.) Arithmetic

+ is addition

Ex. print(1+3) will output 4

   2. - is subtraction

Ex. print(5-4) will output 1

   3. * is multiply

Ex. print(4*5) will output 20

   4. ** is exponent

Ex. print(5**2) will output 25

   5. / is division

Ex. print(6/3) will output 2 — sometimes will output the float type 2.0

   6. % is modulo or remainder

Ex. print(7%2) will output 1

4.) Variables

To assign a variable, use =

An example is:

x = 2

y = 5

print(x+y) will output 7

print(type(x)) will output the < class ‘int’ >

These are examples of what you’ll learn in basic of python - remember, programming depends on experience and always focus on it. Keep practicing and searching will improve your skill at python.

The child’s game, War, consists of two players each having a deck of cards. For each play, each person turns over the top card in his or her deck. The higher card wins that round of play and the winner takes both cards. The game continues until one person has all the cards and the other has none. Create a program that simulates a modified game of War.
The computer will play both hands, as PlayerOne and PlayerTwo, and, for each round will generate two random numbers and compare them.
If the first number is higher, PlayerOne’s score is increased by 1 and if the second number is higher, PlayerTwo’s score is increased by 1.
If there is a tie, no score is incremented.
When one "player" reaches a score of 10, that player should be deemed the winner and the game ends.
The range of numbers should be 1-13 to simulate the values of cards in the deck.

Returns the distance between the current Point object and the given other Point object. The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, y2) can be expressed as the square root of (x2 - x1)2 + (y2 - y1)2. Two points with the same (x, y) coordinates should return a distance of 0.0.
