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。 示例: 输入:(2 -...
在Python中,你可以通过以下步骤来添加两个数字: 定义两个数字变量: 首先,你需要定义两个变量来存储你想要相加的数字。例如: python num1 = 5 num2 = 3 使用加法运算符将两个数字相加: 接下来,你可以使用加法运算符(+)来将这两个数字相加,并将结果存储在一个新的变量中。例如: python sum_result = num...
