非常抱歉,我可能之前漏回答了您的问题。确实,在24点游戏中添加小括号可以增加更多的组合和变化,但是会增加一定的复杂度。
如果要在表达式中添加小括号,可以使用递归函数来尝试不同的括号组合。下面是一个示例代码:
def add_parentheses(expression, depth):
if depth == 0:
return expression
parentheses_expressions = []
for i in range(1, len(expression) - depth, 2):
sub_expression = expression[i-1:i+2]
sub_result = eval(sub_expression)
if isinstance(sub_result, int) and sub_result != 0:
remaining_expression = expression[:i-1] + expression[i+2:]
sub_expressions = add_parentheses(remaining_expression, depth - 1)
for sub_expr in sub_expressions:
parentheses_expressions.append(expression[:i-1] + "(" + sub_expression + ")" + sub_expr)
return parentheses_expressions
def generate_expressions(numbers, operators, num_parentheses):
expressions = []
combinations = itertools.product(operators, repeat=3)
number_perms = list(itertools.permutations(numbers))
for ops in combinations:
for num_perm in number_perms:
expression = "{}{}{}{}{}{}{}".format(num_perm[0], ops[0], num_perm[1], ops[1], num_perm[2], ops[2], num_perm[3])
expressions.append(expression)
expressions_with_parentheses = []
for expr in expressions:
expressions_with_parentheses.extend(add_parentheses(expr, num_parentheses))
return expressions_with_parentheses
numbers = [2, 2, 5, 8]
operators = ['+', '-', '*', '/']
num_parentheses = 1
expressions = generate_expressions(numbers, operators, num_parentheses)
for expr in expressions:
result = eval(expr)
if isinstance(result, int) and result > 10 and result % 24 == 0:
print(expr)
这段代码将根据给定的数字、运算符和括号数量生成所有可能的表达式,并输出计算结果为整数且大于10且能被24整除的表达式。
希望这次能解决您的问题。如有其他疑问,请随时提问!
