Given a linked list and a value x, partition it such that all nodes less than x come before nodes greater than or equal to x.

Given n pairs of parentheses, write a function to generate all combinations of well-formed parentheses.

For example, given n = 3, a solution set is:

Given an array containing n distinct numbers taken from 0, 1, 2, ..., n, find the one that is missing from the array.

0, 1, 2, ..., n

For example,Given nums = [0, 1, 3] return 2.
