L373 Partition Array by Odd and Even
345 Reverse Vowels of a String
125 Valid Palindrome (L415)
75 Sort colors - 3 way patition (L148) - 可以counting sort或者3路归并

L143 Sort Colors II - 用rainbow sort就会像多次3 way partition ?
86 Partition List (L96) - 这个其实不太像partition,不过写着partition所以加到了,比较像linkedlist普通操作
Quick Select :
L5 Kth Largest Element (215) --- 相关703 用heap
L606 Kth Largest Element II - same as above
414 Third Maximum Number -- 可用变量来存,不是特别通用but O(n)
747 Largest Number At Least Twice of Others -- 这题与上一题一样,自己用变量存,其实还真有这类题目。
334 Increasing Triplet Subsequence 这题跟上一题414的解法很像,很容易想复杂。
L80 Median - 可以用divide & conquer, 可以用quick select too ?
