Subrectangle Queries

Implement the class SubrectangleQueries which receives a rows x cols rectangle as a matrix of integers in the constructor and supports two methods:

  1. updateSubrectangle(int row1, int col1, int row2, int col2, int newValue)
    • Updates all values with newValue in the subrectangle whose upper left coordinate is (row1,col1) and bottom right coordinate is (row2,col2).
  2. getValue(int row, int col)
    • Returns the current value of the coordinate (row,col) from the rectangle.
