Answer:
freeware
Explanation:
a freeware is a software that is available free of charge but is not distributed with the source code.
Answer:
# Solve the quadratic equation ax**2 + bx + c = 0
# import complex math module
import cmath
a = 1
b = 5
c = 6
# calculate the discriminant
d = (b**2) - (4*a*c)
# find two solutions
sol1 = (-b-cmath.sqrt(d))/(2*a)
sol2 = (-b+cmath.sqrt(d))/(2*a)
print('The solution are {0} and {1}'.format(sol1,sol2))
Hope This Helps!!!
Cloud computing is more complex than traditional approach due to the following reasons.
Explanation:
1.Cost Savings and Total Cost of Ownership. When you move to cloud computing you tend to save money in several ways in comparison to traditional IT, including the reduction of in-house equipment and infrastructure.
2.Dissatisfaction in Traditional IT. Many companies are frustrated with the negatives that come with traditional IT, such as poor data backup, managing and maintaining your own hardware, and lack of disaster recovery options.
3.Time to Value and Ease of Implementation. Since you don’t have to spend time configuring hardware, maintain systems, and patching software, you can invest your resources elsewhere.
4.Access to Emerging Technology. Much like a car, the minute you purchase on-premise hardware and software, it immediately starts to age. You can access the latest and greatest innovations with a cloud provider who has more purchasing power and stays up-to-date with available solutions. Also, as new innovations are released, they become less likely to integrate with legacy solutions that are often inflexible. Instead, cloud-first development is coming to the forefront.
5.Using Hybrid to Optimize your Operations. Some organizations take the use of the cloud even further by using multiple clouds simultaneously, thus giving them even more agility. Workloads are placed where they perform best, and where costs are most efficient.
Answer:
See explaination
Explanation:
import re
def isValidTrain(train):
pattern = r'^E+(((P|PP|PPP|PPPP)D)*(BB)*)*C$'
if re.match(pattern, train):
return True
return False
def checkAndPrintTrain(train):
print("Train", train, "is valid:", isValidTrain(train))
checkAndPrintTrain("EC")
checkAndPrintTrain("EEEPPDBBPDBBBBC")
checkAndPrintTrain("EEBB")
checkAndPrintTrain("EBBBC")
checkAndPrintTrain("EEPPPPPPDBBC")
checkAndPrintTrain("EEPPBBC")
checkAndPrintTrain("EEBBDC")
Sample output
Train EC is valid: True
Train EEEPPDBBPDBBBBC is valid: True
Train EEBB is valid: False
Train EBBBC is valid: False
Train EEPPPPPPDBBC is valid: False
Train EEPPBBC is valid: False
Train EEBBDC is valid: False
