本题和560. Subarray Sum Equals K非常类似,数组中有负数并不影响。 classSolution {public:intmaxSumSubmatrix(vector<vector<int>>& matrix,intk) {intm=matrix.size(), n=m==0?0:matrix[0].size();if(m==0|| n==0)return0;intres=INT_MIN;for(intr1=0;r1<m;++r1){ vector<int> compress(...
First thing to note is that sum of subarray(i,j]is just the sum of the firstj elements less the sum of the firsti elements. Store these cumulative sums in the array cum. Then the problem reduces to findingi,j such thati<j andcum[j]−cum[i] is as close tokbut lower than it....
