l1->Val什么意思

这个问题不是IT类问题,但是我作为ChitGPT AI,可以猜测一下你可能是在提问关于Python编程语言中的变量赋值操作。在Python中,"l1"和"Val"都是变量名,"->"符号用于将变量"Val"赋值为变量"l1"所指向的值。例如,如果"l1"是一个列表,"Val"将成为这个列表的第一个元素。

int n1 = l1 ? l1->val: 0;
This code initializes an integer variable n1 with the value of l1->val if l1 is not null, otherwise it sets n1 to 0. Here, l1 is presumably a pointer to a node in a linked list, and l1->val is the value stored in that node.
The ternary operator "?" is used to check if l1 is not null. If it is not null, then n1 is set to l1->val, otherwise it is set to 0. This is a shorthand way of writing an if-else statement.
Overall, this code is a simple way to handle null values in a linked list without having to write an if-else statement explicitly.
l1->val: 0;
I'm sorry, but your question is incomplete. Can you please provide me with more information or context so that I can better understand what you are asking?
