LaTeX，显示出问题了么？ 这边显示正常啊。

$$\Large L(n)=\begin{cases}2 & \text{ if } n=0 \\ 1 & \text{ if } n=1 \\ L(n-1)+L(n-2) & \text{ if } n>1 \end{cases}$$

请换一种浏览器试试

乱码部分的内容是： Ln = 2， if n = 0; Ln = 1, if n = 1; Ln = Ln-1 + Ln-2; if n >= 2

Akagi is not only good at basketball but also good at math. Recently, he got a sequence Ln from his teacher. Ln is defined as follow:$$\Large L(n)=\begin{cases}2 & \text{ if } n=0 \\ 1 & \text{ if } n=1 \\ L(n-1)+L(n-2) & \text{ if } n>1 \end{cases}$$And Akagi’s teacher cherishes Agaki’s talent in mathematic. So he wants Agaki to spend more time studying math rather than playing basketball. So he decided to ask Agaki to solve a problem about Ln and promised that as soon as he solves this problem, he can go to play basketball. And this problem is: Given N and K, you need to find \(\Large\sum\limits_{0}^{N}L_i^K\)And Agaki needs your help.
