You are given an array of positive integersarr. Perform some operations (possibly none) onarrso that it satisfies these conditions: The value of the first element inarrmust be1. The absolute difference between any 2 adjacent elements must be less than or equal to1. In other words,abs(arr[...
Another simple way to find the maximum subarray is dynamic programming. If we can use DP to calculate the presum of the array (every subarray with start from the first element), we only need to find the maximum increase in the presum array. We can slightly modify this approach to solve o...
53. Maximum Subarray # 题目 # Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example: Input: [-2,1,-3,4,-1,2,1,-5,4], Output: 6 Explanation: [4,-1,2,1] has the la
All python input is string,so directly input and deal with it.Use "," to split the input array.if the array is divided by space don't need write anything.Nums can be assign value by for loop. FULL CODE PYTHON VERSION: ATTENTION:the minimum value set should use -2147483647,this is the...

We can use a bucket-sort like algorithm to solve this problem in time of O(n) and space O(n). The basic idea is to project each element of the array to an array of buckets. Each bucket tracks the maximum and minimum elements. Finally, scanning the bucket list, we can get the maxi...
