if all the permutations of the array are sorted in one container according to their lexicographical order, then thenext permutationof that array is the permutation that follows it in the sorted container. If such arrangement is not possible, the array must be ...

Can you solve this real interview question? Next Permutation - A permutation of an array of integers is an arrangement of its members into a sequence or linear order. * For example, for arr = [1,2,3], the following are all the permutations of arr: [1,2
Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers. If such arrangement is not possible, it must rearrange it as the lowest possible order (ie, sorted in ascending order). The replacement must be in-place, do not allocate extra memor...
31. Next Permutation 对给定数组,原地将数组存成按字典顺序的下一个数组,字典序最大则输出最小。 33. Search in Rotated Sorted Array 旋转无重复有序数组查找。 34. Find First and Last Position of Element in Sorted Array 对有序可重复数组在O(logN)时间内查找某数出现的下标范围。
The following example may help you understand the problem better: Given the 8 x 8 grid below, we want to construct the corresponding quad tree: It can be divided according to the definition above: The corresponding quad tree should be as following, where each node is represented as a...
