Answer:
class MarblesBoard(object):
def __init__(self, seq):
self.seq = list(seq)
def switch(self):
temp = self.seq[0]
self.seq[0] = self.seq[1]
self.seq[1] = temp
def rotate(self):
temp = self.seq[0]
for i in range(1, len(self.seq)):
self.seq[i-1] = self.seq[i]
self.seq[-1] = temp
def is_solved(self):
for i in range(len(self.seq)):
if i != self.seq[i]:
return False
return True
def __str__(self):
return ' '.join(list(map(str,self.seq)))
def __repr__(self):
return ' '.join(list(map(str,self.seq)))
class Solver(object):
def __init__(self, board):
self.board = board
def solve(self):
steps = 0
while not self.board.is_solved():
if self.board.seq[0] > self.board.seq[1] and self.board.seq[0] != len(self.board.seq) - 1:
self.board.switch()
else:
self.board.rotate()
print(self.board)
steps += 1
print('Total steps:', steps)
Explanation:
The Python class MarblesBoard creates an object of the board game used in the Solver class object instance and it holds data or attributes of the player piece movement and the magic methods (__str__ and __repr__). The Solver object gets the switch and rotate movementt of the player and displays the total steps at the end of the game.
Answer:
Cloud database eliminates the need for establishing and maintaining data centres.
Explanation:
Cloud computing provides an organisation with the infrastructure they need but can not afford. A large online storage with access control policies is available based to subscription.
For a company to establish a data centre, they would need a team of skilled network engineers, fleet of high speed server systems and large storage devices.
The daily power supply and management, coupled with the needed skills and items, can be overwhelming for a company whose main objective is not to deliver database services. So cloud computing is adopted to reduce the cost.
