Description

There is a board with 100 * 100 grids as shown below. The left-top gird is denoted as (1, 1) and the right-bottom grid is (100, 100).


We may apply three commands to the board:

1.WHITE  x, y, L     // Paint a white square on the board,                            // the square is defined by left-top grid (x, y)                           // and right-bottom grid (x+L-1, y+L-1)2.BLACK  x, y, L     // Paint a black square on the board,                            // the square is defined by left-top grid (x, y)                           // and right-bottom grid (x+L-1, y+L-1)3.TEST     x, y, L    // Ask for the number of black grids                             // in the square (x, y)- (x+L-1, y+L-1) 

In the beginning, all the grids on the board are white. We apply a series of commands to the board. Your task is to write a program to give the numbers of black grids within a required region when a TEST command is applied.

Input

The first line of the input is an integer t (1 <= t <= 100), representing the number of commands. In each of the following lines, there is a command. Assume all the commands are legal which means that they won't try to paint/test the grids outside the board.

Output

For each TEST command, print a line with the number of black grids in the required region.
