Listnode newhead null
Web题目描述输入两个单调递增的链表,输出两个链表合成后的链表,当然我们需要合成后的链表满足单调不减规则。基本思路设置一个头结点newHead,newHead初始化乘两个链表中头结点较小的节点。当第一个链表中的节点值小于等于第二个时, 将newHead指向第一个链表节点; 调整正newHea... Web12 apr. 2024 · 刷题小白记录一下, 主要思路: 1.将已有链表反转; 2.若两个链表均不为空,则将不为空的部分相加及进位; 3.若某个链表为空时,另外一个链表不为空,将进位和非空链表相加并链接到头结点; 4.若两个链

Web(1):首先我们保存下一个要反转的节点,因为我们如果不保存的话,prev的初始值为null,当执行完cur.next=prev后,此时相当于链表此时只有一个节点了,那么下一个要反转的节点就丢失了,为了避免这种情况的发生,每次反转前都需要拿curNext指针来保存下一个要反转的节点.即curNext=cur.next
