為什麼要學習演算法？

搜尋引擎：搜尋演算法+排序演算法

推薦演算法：更加方便的得到需要的資訊，機器學習

深度學習：機器學習的一個分支，alphago

學好演算法，才能創造出更有意義的東西

 白板程式設計

資料結構的重要性

algorithms+data structure=program

演算法思想：

• 分治演算法-歸併排序，快速排序...
• 貪心演算法-最小生成樹...
• 動態規劃-最小生成樹...
• 遞迴搜尋-樹形結構...

Donald Ervin Knuth ：
"We have seen that computer programming is an art, because it applies 
accumulated knowledge to the world, because it requires skill and 
ingenuity, and especially because it produces objects of beauty. A 
programmer who subconsciously views himself as an artist will enjoy what
 he does and will do it better."
