Selvan was playing with the a object of random size for stress relief. Selvan knows that the Length, Width, and Height of the object. But he would like to know the surface area of the object he is playing with. Can you help him in finding it?

 #include <stdio.h>

int main()

{

    int length,width,height,surfacearea;

    scanf("%d%d%d",&length,&width,&height);

    surfacearea=2*((width*length)+(length*height)+(height*width));

    printf("%d",surfacearea);

return 0;

}

Elavenil has a chessboard with N rows and M columns. In one step, he can choose two cells of the chessboard which share a common edge (that has not been cut yet) and cut this edge. Formally, the chessboard is split into two or more pieces if it is possible to partition its cells into two non-empty subsets S1 and S2 (S1∩S2=∅, |S1|+|S2|=NM) such that there is no pair of cells c1,c2 (c1∈S1,c2∈S2) which share a common edge that has not been cut.Elavenil does not want the board to split into two or more pieces. Compute the maximum number of steps he can perform while satisfying this condition.
