How a computer encodes text, how it is processed and how computer data is represented.

True or False? At any point in time, an open file has a current file pointer indicating the place where the next read or write o

mr_godi [17]

Answer:

True is the correct answer for the above question.

Explanation:

When any document file is opened then every point has some particular address. so there is a pointer which states that where the read operation and the write operation is going on.
When any person writes any program to read a file or write a file then there is a need for some variable that is pointed for the reading and the write operation.
The document which is used for the write data or read data is also designed and maintained by some software.
Hence we can say that there are needs of some variable that point the operation of the file and it is also stated from the above question. Hence the above question statement is a true statement.

1. Assume that word is a variable of type String that has been assigned a value . Assume furthermore that this value always cont

s2008m [1.1K]

Answer:

1.word = "George slew the dragon"

startIndex = word.find('dr')

endIndex = startIndex + 4

drWord = word[startIndex:endIndex]

2. sentence = "Broccoli is delicious."

sentence_list = sentence.split(" ")

firstWord = sentence_list[0]

Explanation:

The above snippet is written in Python 3.

1. word is initialized to a sentence.

Then we find the the occurence of 'dr' in the sentence which is assign to startIndex

We then add 4 to the startIndex and assign it to endIndex. 4 is added because we need a length of 4

We then use string slicing method to create a substring from the startIndex to endIndex which is assigned to drWord.

2. A string is assigned to sentence. Then we split the sentence using sentence.split(" "). We split based on the spacing. The inbuilt function of split returns a list. The first element in the list is assigned to firstWord. List uses zero based index counting. So. firstWord = sentence_list[0] is use to get first element.

Suppose for the worst case, given input size n: Algorithm 1 performs f(n) = n2 + n/2 steps Algorithm 2 performs f(n) = 12n + 500

melomori [17]

Answer:

29

Explanation:

for n=28:

--------------

Algorithm 1 performs f(n) = n2 + n/2 = 28*28 + 28/2 = 798

Algorithm 2 performs f(n) = 12*28 + 500 = 836

for n=29

--------------

Algorithm 1 performs f(n) = n2 + n/2 = 29*29 + 29/2 = 855.5

Algorithm 2 performs f(n) = 12*29 + 500 = 848

so, for n=29, algorithm 2 will be faster than algorithm 1

The most probable reason why your code for the dog turning right instead of is because your conditional statements are not satisfied.

<h3>What is Debugging?</h3>

This refers to the identification and removal of errors in a given code or hardware component.

Hence, we can see that you should note that you are using teh ifElse conditional statement to execute your code and you stated that the dog would turn right if:

The left side is blocked
If there are balls present.

Therefore, there are balls present and also the left side is blocked which causes your dog to turn right because it is executing the else statement.
