Intro Algo in CS3000 Solve a computational problem Takes in an input(array, number, String and data structure), produce an output(solution, number, String, new array) CLRS Style pseudocode Arrays in CS3000 A = […, …, …] which is similar to Python list, Java/C++ array. index from 1, not 0 Every value in A has a position A = [~,~,~,…,~] pos 1, 2, …, A.length(n) Use for loop to iterate over A for i = 1 to A.length A[i] = -1 Modifying the array in a function(modifies the a) FUNC(A) for i =1 to A ...

Welcome to my blog 欢迎来到我的博客! Introduction I am Shuntian Yang(杨舜天), a 1st-year computer science student at Northeastern University. I was born in a nice tiny city called Haian in Jiangsu, China. To share my experience and thoughts in the way of studying CS and my wonderful life. That’s the reason I build this website! Hope you can have fun here！ Future plan Recently, I am taking the class of CS3000 Algorithm & Data and CS3800 Theory of Computation. I am gonna post my summarized notes and hw ...

Intro First of all, we need to know the points of TC: Understanding limits of computers how machine solve problems Practical — Conceptual frameworks that can be put into practice grammars of programming language regular expressions in pattern matching NP-Completeness tells which problems aren’t tractable Timeless Frameworks are resilient to changes in technology Simple – Theory strips away complicated aspects of computing! Foundational – Theory is interesting on its own! Tons of ...
