2. Add Two Numbers 两数相加 给出两个非空的链表用来表示两个非负的整数。其中,它们各自的位数是按照逆序的方式存储的,并且它们的每个节点只能存储一位数字。 如果,我们将这两个数相加起来,则会返回一个新的链表来表示它们的和。 您可以假设除了数字 0 之外,这两个数都不会以 0 开头。
解析 def add_two_numbers(a, b): return a + b 需要编写一个Python函数计算两个整数和。函数名确定为add_two_numbers,参数设为a和b。整数相加可直接使用+运算符,返回a + b即可。函数结构符合Python语法要求,参数明确,能实现所需功能。无需异常处理或类型检查,题目未要求额外功能。该方案直接且正确。
