Answer: hello your question lacks the required option, below are the missing options
A. The transaction data in the tampered block is deleted, and a copy is created with the same hash value.
B. The hash values of transaction data of subsequent blocks are validated, and the chain is broken.
C. The hash value for the entire block is nullified, creating a domino effect on all subsequent blocks.
D. The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues.
answer : The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues ( D )
Explanation:
What happens if a transaction data is changed in an earlier existing block in a Blockchain is that the Hash values of subsequent blocks will be updated as soon as they are tampered with and the chain will continue.
Blockchain is a specially design system for recording information, hence any change in data inputted in an earlier existing blocks that changes will automatically be updated as well in all preceding blocks.
Answer:
A linear search is one that scans every record/file until it discovers the value being searched for.
Binary search, on the other hand, is also known as <em>Logarithmic search</em>. It is used to locate the position of a value inside an array that has already been sorted.
The linear search will return the lowest value faster than the binary search when small arrays are involved.
This will only be feasible when the array is sorted prior.
Cheers!
Hi! I'm a Digital Marketer Intern at hotels.ng and I have a moderate knowledge on programming.
First, your question is not very explanatory. The term "view" is often used in back-end web development. A view is simply a Python function that takes a Web request and returns a Web response.
But I'm not sure this is what you want, so I'll just go ahead and write a python function involving class to return the total number of credits taken by a student.
I'll answer this question using Python.
class student(object):
credits = None
year = None
def num_credits(self):
#get credit value
self.credits = input("Enter the total number of credits: " )
pass
def getYear(self):
self.year = input("Enter current year: ")
pass
def tot_credits(self):
TotalCredits = tempTotalCredits + self.num_credits
print "Your total credits are :"+" "+str(TotalCredits)
