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
从0 开始的排列nums是一个由0到nums.length - 1(0和nums.length - 1也包含在内)的不同整数组成的数组。 Given a zero-based permutation nums (0-indexed), build an array ans of the same length where ans[i] = nums[nums[i]] for each 0 <= i < nums.length and return it. A zero-based...
Given an array of positive integers arr (not necessarily distinct), return the lexicographically largest permutation that is smaller than arr, that can be made with exactly one swap. If it cannot be done, then return the same array. Note that a swap exchanges the positions of two numbers arr...
Permutation II https://leetcode.com/problems/permutations-ii/ Constraint: Arrays may not be sorted May contain duplicate Return order is arbitrary Idea The difference with Permutation I is how to avoid adding duplicate permutations. Based on the graph below, each permutation can be seen as a ...
