Sub Matrix Sum Queries Interviewbit, Instead of calculating sum for each submatrix of size B x B one by one, we can use a different strategy. The code is merely a snippet (as solved on InterviewBit) & Given a matrix of integers A of size N x M and multiple queries Q, for each query find and return the submatrix sum. Then, for each query, traverse all Given a matrix mat [] [] of size n × m and a query matrix queries [] [] of size q × 2, where each query queries [i] = [a, b] represents the Contribute to Vivek27951/InterviewBit development by creating an account on GitHub.
