Segment Tree is used to answer range queries in an array. The data structure can be extended to 2 dimensions to answer sub-matrix queries in logarithmic time. Some examples of these queries are :

  • Maximum/minimum element in sub-matrix
  • Sum of elements in sub-matrix
  • XOR of elements is sub-matrix
