My first reaction is HOW.After think it over,I found I just miss something tricky.In the process of iteration,we could hit a position whose subarray sum is negative(say i,then array[0]+...+array[i]<0),then we can and should throw this part away.It is because negative sum would co...
利用快速排序的思想,从数组S中随机找出一个元素X,把数组分为两部分Sa和Sb。Sa中的元素大于等于X,Sb中元素小于X。这时有两种情况: 1. Sa中元素的个数小于k,则Sb中的第k-|Sa|个元素即为第k大数; 2. Sa中元素的个数大于等于k,则返回Sa中的第k大数。时间复杂度近似为O(n) publicvoidfindk(int[] nums...
Given an array which consists of non-negative integers and an integer m, you can split the array into m non-empty continuous subarrays. Write an algorithm to minimize the largest sum among these m subarrays. **Note:**If n is the length of array, assume the following constraints are sati...

一、原题:410. Split Array Largest Sum 方法一、动态规划 「将数组分割为mm段,求……」是动态规划题目常见的问法。 f[i][j]: 表示将数组的前i个数分割为j段所能得到的最大连续子数组和的最小值。 sub(i,j): 表示数组nums中下标落在区间[i,j]内的数的和。

array one by one. For each element num, if sum + num <= x, it means we can add num to the current subarray without exceeding the limit. Otherwise, we need to make a cut here, start a new subarray with the current element num. This leads to an increment in the number of subarray...
