请用python实现鸡兔同笼算法求解

鸡兔同笼算法是一个经典的数学问题，可以用Python来实现。下面是一个示例代码：

def solve_cage(num_heads, num_feet):
    """
    Solve the chicken-rabbit cage problem, given the total number of heads and feet.
    """
    for num_chickens in range(num_heads + 1):
        num_rabbits = num_heads - num_chickens
        if (num_chickens * 2 + num_rabbits * 4) == num_feet:
            return (num_chickens, num_rabbits)
    return None

# Example usage: print the solution to the problem with 35 heads and 94 feet
print(solve_cage(35, 94))

该代码使用了简单的循环来枚举可能的鸡和兔子的数量，并检查它们的头数和脚数是否与给定的值匹配。如果找到了一个解，则返回一个包含鸡和兔子数量的元组；否则返回None。
