唯一的边界条件是如果全部为负数,那么minsubarray = sum,这个时候直接返回max即可。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 public int maxSubarraySumCircular(int[] A) { int n = A.length; int sum = 0; for (int num : A) sum += num; int max = A[0]; int[]...
=max(Max(A[i]), sum-sum)=0 含义为:Max subarray为空数组。 显然不满足题意。 因此,在这种情况下,我们要求的最大和,只能是Max(A[i])=allMax 代码参考: 1classSolution {2public:3intmaxSubarraySumCircular(vector<int>&A) {4intsum=A[0];5intcurMax=A[0], curMin=A[0], allMax=A[0], ...

Maximum Subarray Sum 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...
