在职刷题战拖，要被温水煮熟了！！

## 10/12/2018 Friday
Tag: DP 2 Hard + 1 Medium
* 354.Russian Doll Envelopes (transform to longest increasing subsequence, dp + binary search, O(nlogn)
* 740.Delete and Earn (sort, group same value elements, transform to game on value bucket array)
* 321.Create Maximum Number (maximum subsequence; merge)

今天效率超低。。740 和 321都debug超级久。说好的限制时间呢。。太喜欢死磕了

## 10/13/2018 Saturday
Tag: DP 1 Hard + 1 Medium
* 132. Palindrome Partitioning II

下周末回国，今天准备东西跑了一天。。

## 10/14/2018 Sunday
Tag: DP 1 Hard + 2 Medium
* 213.House Robber II
* 403.Frog Jump （dfs + memoization; bfs)
* 368. Largest Divisible Subset （dp输出最佳方案）

这个周末因为准备下周末回国耽误了刷题时间，比weekday刷的还少。。。

dp tag下面一些dfs backtrack的问题写起来磕磕绊绊，下一个tag该dfs了！

谢谢各位大佬的大米！路过的朋友来保持队形啊~

周六上午的飞机回国，周四到周日请假！今天还得去买行李箱。。

回国6天，一直在奔波，倒时差，昨天H1B首签还被check！只有飞机上抽出时间看了一个tag的资料，完全没找出时间刷题。。希望这个周末之后回到家能稳定刷题时间
