Maximum Subarray Sum 题意 给你一个大小为N的数组和另外一个整数M。你的目标是找到每个子数组的和对M取余数的最大值。子数组是指原数组的任意连续元素的子集。 分析 参考 求出前缀和,问题变成了O(n*n)复杂度的问题,但是仍然不能解决问题。 设prefix为前缀和,设i < j,一般都是通过算sum = prefix[j] - prefix[i]
/* Given an array nums and a target value k, find the maximum length of a subarray that sums to k. If there isn't one, return 0 instead. Note: The sum of the entire nums array is guaranteed to f...Maximum of Maximums of Minimums 点击打开链接 You are given an array a1, a2...
907. Sum of Subarray Minimums # 题目# Given an array of integers A, find the sum of min(B), where B ranges over every (contiguous) subarray of A. Since the answer may be large, return the answer modulo 10^9 + 7. Example 1: Input: [3,1,2,4] Output: 17 Explanation: Subarray...
Given an array of n positive integers and a positive integer s, find the minimal length of a subarray of which the sum ≥ s. If there isn't one, return 0 instead. For example, given the array [2,3,1,2,4,3] and s = 7, the subarray [4,3] has the minimal length under the ...
Maximum subarray sum The maximum sum subarray problem consists in finding the maximum sum of a contiguous subsequence in an array or list of integers: max_sequence([-2, 1, -3, 4, -1, 2, 1, -5, 4]) #…
So I change the format of the sub problem into something like:maxSubArray(int A[], int i), which means the maxSubArray for A[0:i ] which must has A[i] as the end element. Note that now the sub problem's format is less flexible and less powerful than the previous one because the...
Maximum Size Subarray Sum Equals K Given an arraynumsand a target valuek, find the maximum length of a subarray that sums tok. If there isn't one, return 0 instead. Example 1: Givennums=[1, -1, 5, -2, 3],k=3, return4. (because the subarray[1, -1, 5, -2]sums to 3 and...
The maximum subarray problem is the task of finding the contiguous subarray within a one-dimensional array of numbers (containing at least one positive number) which has the largest sum. For example, for the sequence of values −2, 1, −3, 4, −1, 2, 1, −5, 4; the contiguous...
