题意

给你两个二进制串,求其和的二进制串。

题解

思路1

按照小学算数那么来做,用 carry 表示进位,从后往前算,依次往前,每算出一位就插入到最前面即可,直到把两个二进制串都遍历完即可。 ```go func deleteDuplicates(head ListNode) ListNode { if head == nil || head.Next == nil { return head }

curr := head

for curr.Next != nil {
    if curr.Next.Val == curr.Val {
        curr.Next = curr.Next.Next
    } else {
        curr = curr.Next
    }
}

return head

}
