Given n Balloons, indexed from 0 to n-1 . Each balloon are painted with a number on the IT represented by array nums . You is asked to burst all the balloons. If The burst balloon you'll i get nums[left] * nums[i] * nums[right] coins. Here and is left right adjacent indices of i . After the burst, the and then left rig

Given an array S of n integers, is there elements a, b, c in S such That a + b + c = 0? Find all unique triplets in the array which gives the sum of zero.Note: Elements in a triplet (a,b,C) must is in non-descending order. (ie, a ≤ b ≤ c) The solution set must not contain duplicate triplets. For example, given array S = {-1 0 1 2-1-4}, A solution set is: ( -1, 0, 1) (-1,-1, 2)Idea: If the direct use of triple traversal brute force crack, the time complexity of O (n

#198 House RobberYou is a professional robber planning to rob houses along a street. Each house have a certain amount of money stashed, the only constraint stopping all from robbing each of the them are that Adjac ENT houses have security system connected and it would automatically contact the police if the adjacent houses were bro Keninto on the same night.Given a list of non-negative integers representing the amount of money in each house, determine the maximum amount of mone Y you can rob ton

); } }The result of its operation (you can compare it with the GIF image above):iv. permutations and combinations1, the output of any number of letters, the full array of numbersAn array of strings of n or n characters (numbers, nodes) that have a total permutation of a (n, n) =n! species. This problem is also a recursive problem. For example, the full array can be obtained: {123,132,213,231,312,321}.The following code is implemented with the recursive algorithm: Public Static voidPermutati

TopicGiven an array S of n integers, find three integers in S such, the sum was closest to a Given number, target. Return the sum of the three integers. You may assume this each input would has exactly one solution.For example, given array S = {-1 2 1 -4}, and target = 1.The sum that is closest to the target is 2. (-1 + 2 + 1 = 2).AnalysisThis question is very similar to the previous one. The sum of the ternary elements closest to the target value in an integer array sequence is obtained.The sol

Topic one: Given an array of length n, find the longest monotonically incrementing subsequence (not necessarily contiguous, but not in a chaotic order). and returns the length of the monotonically increasing subsequence. For example: Given an array of length 8 a{1,3,5,2,4,6,7,8}, its longest monotonically incrementing subsequence is {1,2,4,6,7,8}, and we return its length 6. Topic Two: On the basis of topic one, we want to return the elements in the subsequence. For example, given an array

Suppose a sorted array is rotated on some pivot unknown to you beforehand.(i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2 ).You is given a target value to search. If found in the array is return its index, otherwise return-1.Assume no duplicate exists in the array.Solution 1: Sequential lookup, Time complexity O (n).class Solution {public: int search (vectorintint Target) { int0; while (I Nums[i]) i+ +; return i

Original title address: https://leetcode-cn.com/explore/interview/card/top-interview-questions-easy/1/array/21/Title Description:Given a sorted array, you need to delete the repeating elements in place so that each element appears only once, returning the new length of the array after removal.Instead of using extra array space, you must modify the input array in place and complete it with O (1) Extra space.Example 1: Nums 1 2 . You do not nee
