A single expression that will return true if the lower four bits of x are the same as the lower four bits of y is; (x & 0x0F) == (y & 0x0F)
<h3>How do you write single expression programs?</h3>
There are different methods of writing programs such as python and others. However, in this case, it is pertinent to know that this compiler that will return true if the lower four bits of x are the same as the lower four bits of y doesn't accept binary constants and as such we will use hexidecimal instead. For example; for 0b00111111, we will use 0x3F.]
Thus, using that same concept above, the single expression that will return true if the lower four bits of x are the same as the lower four bits of y is; (x & 0x0F) == (y & 0x0F)

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:
Colleges care a lot more about your math skills than computer stuff, even for computer science. Make sure you still do some computer science stuff (esp. if it's extracurricular) but focus on improving your math.
