Consider binomial tree model. Suppose that $n = 50$, $p = 0.7$, $S(0) = 140$, $u = 0.08$, and $d = -0.04$. What do you think of $S(50)$? Use computer for your calculations and graph. Show your work clearly. Your answer should include
1. Matlab / Python / C / C++ code
2. Output
3. $S(50)$ distribution graph
4. Interpretation / discussion
