将一个混合了字符和数字的链表分成两个链表：字符链表，数字链表

好的，可以通过遍历链表，将字符节点和数字节点分别加入到两个新的链表中。具体实现可以参考以下代码：

class ListNode:
    def __init__(self, val=0, next=None):
        self.val = val
        self.next = next

def splitList(head: ListNode) -> tuple:
    char_head = char_tail = ListNode()
    num_head = num_tail = ListNode()
    while head:
        if isinstance(head.val, str):
            char_tail.next = head
            char_tail = char_tail.next
        else:
            num_tail.next = head
            num_tail = num_tail.next
        head = head.next
    char_tail.next = None
    num_tail.next = None
    return char_head.next, num_head.next
