# 学习笔记

+
+第一周听完老师讲解,不敢想,就是一门外汉,凑看热闹了,实在的之前没有接触算法类工作实践,
+而学习积累也缺乏算法的阅读和思考,印象比较深的是2年前工作实践,使用了一个递归,后面想想才觉得是。
+因此,编程算法虽说实际应用比较,但有的话,用起来就不一样,那次使用递归完整权限的工作,花费过多时间,
+才得以实现。
+也算是进来了这个课堂,模糊知道了学习态度与现有能力的差距,已经是第三周了,题目还没按量完成,
+直至现在07.03才意识到自己推送代码上还存在问题,学习惰性太强了,学习难度也在,还是得加把劲,
+在过程中也要挖掘其中乐趣,找到自己所热爱的事情,为之燃烧。__2019.07.03 Thu

+回想了下,自己做的第一道题目,足足坚持了三天,是挤出清晨+夜晚得时间去思考+动手尝试,
+才把题目解出来,想想,前人已经把题目解决,有比我更好得解答速度+高效得解决方案,为何我还在花费三天
+的时间在这些重复问题上???
+学习速度慢+差距巨大+学习难度高,也许是我目前遇到的问题,另外,思考我自己真正想做的、热爱做的事情也许才是
+更加重要的事情,我上线下课已经有想法,想知道超哥的过往以及个人价值观+追求,
+且行且思考,唔生有崖而学海无涯。加油! __2019.07.03 (补)

+本周做题极度缓慢了,学习的热火已经如蜡烛般微弱,应该是学习的乐趣和自我激励上没有达到。
+另外个人惰性也开始回来了,当然这个是相较于第一周时学习的热情,因为,在老师直播评价其他同学
+作业中,也看见了他人提交作业的质量、数量上也是大大超出自己想象,在老师感到欣慰的同时,我个人
+学习的意向好像被眼前的他人的成绩打败了,差距真的越拉越大的感觉,有时真的,一道简单的二叉树,
+自己也是想了好三天。
+在这周自己也学习广州的同学,约了深圳线下一名高手,几乎每周的题目刷个光,而且还有自己的自主选择,
+一些较为偏僻的题目,就先暂缓花时间上去,这个对于我们成年人、已工作人士而言,也比较确切的问题,
+时间的宝贵性,在持续的努力过后,收益甚微,会极大挫伤走下去的勇气。
+说到实质上的问题:
+1、上下班后精神、体力、脑力的下降
+2、算法与数据结构的基础薄弱
+3、计算机基本素养有待提升
+4、对于学习职业规划,个人发展,以及目前的学习算法,少了恒心
+收获:
+二叉树的递归求深度稍微了解。

+最后一周的作业,在调休的周一,坚持了一天的情况下,超常完成了三道题,当然是
+在自己思考无果的情况下,借鉴了题解以及相关的评论然后完成,在自己思考尝试没有完成测试,
+偷看他们的做法,会得到一种震撼感,真的人家的孩子,不是没有道理的,感觉他们是真算法了,
+自己的拖拉机式思考,完全完完全全被击败了,难得自己今天调休可以在外面待上一个白天,但是
+我们时间不多了,人生的事情还很多,钱包还没鼓起来,真的是有时做题也是挺高成本的,但是不做,
+待在屋里貌似也不会有太大的进展,
+还是出外结识一些朋友,做业务,在其他方面腾飞吗?发展吗?
+今天在深圳音乐厅的星巴克附近,发生两起,
+一个是在大中午的闹事,被Sir抓啊,喊啊,想想也是累啊
+另外一个就是,两个类似三和大神的人物,就赖在椅子上睡了起来了,其实,大热天的,
+我也是溜出来叹空调,可是,老哥他更厉害,直接睡上了,
+芸芸众生啊,苦生相,
